Types and parts of pressure control valves

Industrial / May 6, 2017

Parts of pressure control valve

Generally speaking there are two important parts of pressure control valve. These are explained as under:

  • Valve is the first part which allows the fluid flow through it. It is that part which also varies the flow magnitude.
  • The controller is the other part. It signals the valve to increase or decrease the sizing Technically speaking valve operates under the commands or signals which are generated by the controller.
  • As per some experts the actuator is the third part of the pressure control valve. The opening and closing of the valve are controlled by this part.

Types of pressure control valves

As the manufacturers flood the market with pressure control valves there are many types which can be purchased. Some of these are mentioned as under for clarification in a better manner:


  • Globe valve

Flow regulation in a pipeline is controlled by globe valve. There are two openings of this valve that are separated by a baffle. The disk on the top is rotated to regulate the flow manually if they are being used for home. As the disk is moved the rings inside slide down and completely or partially stop the fluid or water flow. Industrial globe valves are embedded with a long pipe. This is installed between the baffle and the disk. The industrial type also comes with the actuator to control the fluid flow and maintain the hydraulic pressure.


  • Butterfly valve

There is a large disk installed to control the fluid flow using butterfly valve. There are several advantages of using this valve. Some of them are:

  • These valves support instant shut off. This means that when installing to any hydraulic system it allows resource saving.
  • Among all types of valves this one has the lowest cost and therefore it is used in a number of industries including hydraulic power stations and cement factories.
  • As compared to other types this one is very light in weight. It therefore does not require any special equipment for installation neither it requires special installation arrangements.


  • Ball valve

It is the most common type of valve that is used in industrial applications. It is also one of the most used valves for home piping and fluid control. A hollow ball is used to control the fluid that is passing through the pipes. When the ball hole is in line with the flow the valve is considered open. The handle at the top allows the closing of the valve manually. Most industrial shut-off and control applications use this valve. They are very reliable in nature and therefore remain in the best form even after long disuse periods.

Depending upon the use and equipment in the industry any of the above-mentioned valves can be used. There are other types of valves as well which can fulfill the purpose such as gate valve, piston valve, hydrogen valve and pinch valve. The working of valve greatly depends upon materials that are used to make them. Normally valves are made up of titanium, chrome, bronze and brass.

Ultrasound In Action: Unparalleled Cleaning Results

Industrial / November 23, 2015

Surface cleaning by ultrasound is referred to highly effective and efficient purification and cleaning processes. The advantages of this method are: the ability to quickly remove various types of pollution from the surface of the items; ability to clean parts of complex shape, with hard to reach cavities and channels; applicability of different detergents; possibility of carrying out the cleaning process at room temperature or moderate heating; ease of mechanisation and automation of the process.

Ultrasonic waves propagating in detergent solution from the radiation source, provide pressure on the surface of the item due cavitation phenomena. Cavitation is manifested in the fluid breaks under the action of the sound wave to form small bubbles (50-500 microns) filled with cleaning fluid vapors. Some bubbles collapse almost instantly (20-50 ms), creating a local pressure surges reaching the pressure of hundreds of atmospheres. Under the influence of this pressure the destruction of contaminants takes place. Another part of bubbles doesn’t collapse, and under the influence of intense pulsed ultrasound field and moves with the hydrodynamic flow, it contributes to the intensification of treatment.

Choosing the optimal procedure

Depending on the type of contamination (solid or liquid), and a kind of washing medium (solvent or alkali aqueous solution) cleaning mechanism is determined. Thus, the purification of solid contaminants in the aqueous environment pollution destroyed forces arising in the collapse of bubbles. When cleaning in a solvent or aqueous medium-soluble or viscous pollutants most important is the circulation of the fluid in which the major role is played by active pulsating bubbles. The main factors determining the cleaning process are: the frequency and intensity of ultrasonic vibrations, the properties and temperature of the cleaning liquid and the location of the parts to be cleaned in an ultrasonic field.

The frequency of the ultrasonic vibration determines the intensity of the collapse of cavitation bubbles. The lower the frequency, the greater the intensity of each separate act of collapsing, as at low frequency the bubble has more time to form and reaches a higher value. Furthermore, at low frequencies waves have a large penetration depth, which is particularly advantageous when cleaning complex parts having holes and chambers. Under the influence of low-frequency ultrasonic waves can have a vibrate effect on components themselves, which also contributes to cleaning.

However, at frequencies below 20 kHz, the sound becomes audible. The shrill sound of the whistle and the accompanying job ultrasonic devices on these frequencies is unpleasant for the human ear and has a painful impact. Based on the above assumptions, studies and technical expertise, the frequency of 20-25 kHz is the most appropriate for cleaning. This is the optimal number manufacturers are heading for – Hilsonic engineers, representing one of the most influential UK manufacturer of ultrasonic cleaner equipment, admits the numbers lie within the golden medium they are aiming at in designing and production.

The role of concrete throughout ages

Industrial / November 10, 2015

Like most building materials, concrete has come through a long way of development and enhancements. In the excavations on the banks of the Danube archaeologists discovered the remains of habitation 5000 years ago, where the 15” thick floors were a prehistoric pouring concrete: as binder red clay was used, while the reinforcing element was a fine river gravel.

Egyptian civilisation

Specific examples of the binding of small stones or solutions with coarse aggregate were known in ancient times to the Egyptians, the Babylonians, the Phoenicians and Carthaginians. The earliest use of concrete in Egypt was found in the tomb of Thebes, and it dates back to 1950 BC. Concrete was used in the construction of the Egyptian galleries of the maze (3600 BC) and the monolithic body of the pyramid Nima long before our era. The Egyptians used gypsum and lime as a binder. A quarter century ago, Swiss chemistry professor Joseph Davidovits made a resonance assumption that artificial production of geopolymer concrete blocks took place in the erection of the pyramid of Cheops. Examining limestone blocks, a professor found a human hair in one of them – it could be there only in one case: it fell off when mixing the working solution. The result of further searches of the scientist was the inscription on the stele period of 3rd dynasty. Decoded characters contained recipes of ancient concrete. An independent study found that the base of the Great Pyramid is built of natural limestone and the top few rows are made of concrete. A concrete mixture comprises a palm ash, sandstone chips and a variety of soda obtained from the Nile water.

Concrete in Asia

In India, in the temples and palaces of the nobility well-preserved concrete printed floors (of IV-V centuries BC) were found. One of the first concrete materials was applied the ancient Chinese people. Great Wall of China, the construction of which began in the 3rd century BC. was partially built of concrete. Preparation of concrete and forming of a wall can be described as one part lime putty thoroughly mixed with two parts of sand and gravel, then such a dry concrete mix with a small amount of water was stacked in layers of a thickness of about 7” between the wooden boards of formwork and compacted hard wood beetles. The next layer of concrete was laid on the damp of surface.


Сoncrete use is widely spread across the world, and it is utilised for the construction of various structures. The material is used in the construction of both residential and industrial buildings as well as in road construction, construction of bridges, tunnels and hydraulic structures. The material itself has numerous modifications, thus the most advanced, like Telling architectural agency based in Wolverhampton, focus on hydraulic lime and lime mortar solutions.

The use of concrete in construction helps architects to express their creative ideas and plans. Also, when using a matrix with different patterns an architect can create a textured surface that does not require additional finishing. As the use of concrete mixtures in construction contributed to the creation and dissemination of various formwork systems.

Slant Wells Profile Types & Choice Features

Industrial / November 9, 2015

The correct choice of the borehole in directional drilling is the mission of essential importance. Rational profile allows minimizing the work of deflection arrangement to the least possible depth, provides the necessary offset relative to the outfall of the allowable deviation intensity, the free passage of the drilling equipment through tubing, as well as trouble-free well exploiting in accordance with modern methods for long time.

Consequently, the profile of downhole must be chosen with minimum time consumption, investment volumes, allowing achieving the required a depth with no change project adjustments and accidents, ensuring adequate quality for long and trouble-free operation.

Nowadays are widely used and meet virtually all the geological, technical and technological requirements of drilling and production profiles of the following types:

  1. The tangential type of profile features three sections: vertical section, section of a set of zenith angle, site stabilization zenith angle extending to a depth of wells. This profile provides maximum deviation from the vertical wellbore with a minimum zenith angle, so it is preferred to use it in the case of multiple drilling. The profile either does not imply using any intermediate columns in wells of moderate depth or implies curvatures within the range provides in case of deep wells;
  2. S-shaped type of profile consists of four sections: vertical section, section of a set of zenith angle, site stabilization zenith angle and zenith angle falling area. The hallmark of this profile is the presence of a set of plots and the zenith angle of incidence, so in addition to the general 5-interval, 3 and 4-interval modifications are possible. This profile is taken advantage of when the need to establish intermediate casing strings, drilling wells from one platform, for example, on the high seas, is required. This profile provides an intermediate casing in the range of the second deviation.
  3. J-shaped is the type of profile consisting of two sections: a vertical section and a low-intensity set zenith angle along the major radius. The profile is used for drilling on layers beneath the salt domes, multiple drilling and opening the deep-lying objects.

Tangential and J-shaped profile types are typically preferred to the S-shaped so that they have no kinks; they improve the permeability of the tool and geophysical instruments, reduce the amount of work the deflection arrangement reduces the resistance force when moving the drilling and casing facilitates operating conditions well.

However, the proven industry experts will carry out a thorough examination prior to proceeding to initiating the works. A full development cycle in fact can be delegated to a single company: thus, if you are searching for a company to outsource borehole drilling tasks, you may want to consider the option of teaming up with European Geophysical Services. A seasoned company specializing in geophysics, boasting a triple A staff and an affordable pricing model, has been in borehole drilling for more than 9 years. The company will cope with a borehole drilling mission of any complexity, so feel free to get in touch with EGS reps to discuss the details.

Ultrasonic Cleaning Efficiency At Pipelines Under The Roof

Industrial / October 20, 2015

To press for the maximum efficiency from using ultrasound technology, continuous ultrasonic cleaning and a conveyor belt in particular are typically used in the manufacturing process. These settings are more productive and are used for machining high-volume production.

Depending on the contamination of parts cleaning process might look like and consist of the following cleaning cycles:

1) cleaning in boiling solvent; ultrasonic cleaning; cleaning in pairs, drying;

2) ultrasonic cleaning; cleaning in pairs, drying;

3) wetting the cold solvent; ultrasonic cleaning; cleaning in pairs, drying;

4) ultrasonic cleaning; cleaning in boiling solvent;

5) cleaning in boiling solvent; cleaning in boiling solvent without ultrasound; cleaning in boiling solvent;

6) cleaning in boiling solvent; wetting cold solvent without ultrasound; cleaning in pairs.

The first cycle is most preferred as it demonstrates the most admiring results in terms of cost-efficiency. Cycles two and three are used in cases where purification is conducted by thermosetting contaminants which are polymerized in boiling solvent. The cycle of four may be used to flush out dirt deeper into the details, peeling from the surface contamination when exposed to ultrasound. In this case, the condensate is collected in a separate section.

Nevertheless, the efficiency marks may be different in sophisticated cases. Therefore, before integrating the technology the possible options are investigated along with equipment manufacturer’s experts. The most innovative businesses, like Hilsonic, focused on ultrasonic cleaner devices production, provide consulting and professional audit services to help the companies make the most of the transition.

Cleaning security should be provided with ventilation devices. In case of solvent vapor breaks above refrigerator suction with a subsequent release into the atmosphere which leads to pollution of the atmosphere. It is therefore preferable to block the ventilation system. (more…)

All You Should Know About Lifting Crane Equipment

Industrial / September 13, 2015

Currently, virtually all the varieties of hoisting units are in demand – regardless of whether it is electric and manual equipment. Perhaps, the leading roles in industrial spheres are played by overhead electric double-girder or overhead traveling cranes. In cranes construction the number of beams defines the lifting capabilities of the equipment. For example, double-girder overhead traveling cranes are used in those cases when there is a need to transport cargo weighing more than 10 tons. In the same case, when the weight of the load is relatively small, single-beam suspension design is quite suitable. Electrical control of lifting equipment, in contrast to the manual one, it provides greater productivity and is characterized by higher wear resistance. The installation of such units shall is based on a wide array of requirements, including fire safety, performance safety and many more.

Installation aspects

With the professional installation the customers reduce the risks breakage and equipment failure, getting more confidence in the integrity and safety of the equipment, and most importantly, the health and lives of employees. As a rule, in case of minor breakages, the repair of bridge cranes (both double-girders and single-beam devices) is carried out not only cost-efficiently, but also in a very short period of time, which has a paramount importance for production. Certain equipment types, especially custom ones, are even backed with the lifetime warranty.

Industrial facilities construction almost inevitably implies utilising a range of lifting equipment. The market of lifting cranes provides you with myriads of options, and to make a proper choice you should be guided by a long list of variables. Perhaps, the most widely applied design is hoist crane, which is confirmed by the statistics – thus, Granada Material Handling, an innovator of lifting equipment manufacturing, admits the bestselling products as for 2014 where gantry hoist and overhead crane devices. Currently, this type of lifting equipment is successfully applied in vessels construction and a huge variety of prefabricated buildings construction. Custom equipment accounts for nearly a half of sales; in general the core benefits of custom projects lie in boundless opportunities, allowing servicing the most sophisticated areas and meeting the most complicated requirements.

The pricing model

Like dozens of other lifting equipment options, gantry cranes come with a huge number of design features. Runway is the basis for strong pillars and the main part of the structure. The price of a gantry crane is largely defined by performance and functionality capabilities (the cost can be largely impacted by control panel design). An overwhelming majority of manufacturers concentrate their efforts on producing equipment that handles up to 500 tons and provide the 30-35 meters height lifting. The installation procedure of automatic equipment is narrowed to programming the control panel, making the interaction with the equipment as user-friendly as possible.

For the storage areas the lifting mechanism with a fixed cabin is preferred, while in other operating conditions mobile cabin or even radio control can be more effective. Normally, the installation and repair of gantry cranes is provided by the manufacturer (in some cases even lifetime guarantee on crucial parts is provided).
