b2ap3_thumbnail_connection-ends-valves.jpgThere are various types of end connections that a valve can have. Depending upon the types of applications the valves are being used for, you can choose the right type of end connections. The common types of valve end connections are as follows:

Flanged Valve End Connections – These are one of the easiest connections to be installed or uninstalled from a pipeline. These are also one of the most commonly used end connections at present. As these are fastened to the pipe flanges, assembling or disassembling them is quick and easy. These are usually available in sizes from 15mm onwards. An important point to be mentioned about these types of end connections is that they are secured with several bolts. Thus, they ultimately need less tightening torque than what a threaded end connection requires. Hence, flanged end connections can be effectively used for various types of valves.

Threaded Valve End Connections – These types of end connections are suitable for low pressure piping systems. These are affordable and ensure quick assembly to the users, without any difficulty. In some cases, these connections may be welded around the joint, once they are assembled. However, this is not much in practice as it may cause some troubles in the efficient use of these types of valve end connections.

Socket Weld Valve End Connections – These types of connections are socketed so as to have a plain spigot end of the pipe. These are used on valves that are made up of steel, and for such applications that require higher pressure and/or higher temperature in pipelines that do not necessitate repeated disassembling. They ensure leakproof connections, that too for a long time span.

Butt Weld Valve End Connections – These types of end connections are manufactured in such a manner that each end of the valve is bevelled to match with the thickness and bevel on the pipe.   After this, the two ends are butted to the pipeline and are welded. They are used on steel valves, and as they have greater strength, they are perfect to be used for such applications that require higher pressure and/or temperature in pipelines. Also, these are ideal for all types of valves, and for use in those areas where repeated dismantling is not required.

You can easily find a reputed and well-known provider of these different types of valve end connections on the internet such as the Valtorc International. Such suppliers have various experts with them, who will help you pick the right products for your preferred areas of application.  So, contact the right manufacturer and get the most suitable valve end connections for your use.

b2ap3_thumbnail_0108.gifBefore understanding the concept of a solenoid valve, we should first understand what a valve is.

A valve is a device which works by regulating or controlling the flow of a fluid. This fluid can be liquid, gas, slurry, etc. Valves are available in a wide variety of makes and designs, serving a variety of purposes.

Now, a solenoid valve is just the combination of a solenoid and a valve, which regulates the movement of gas or liquid by means of electric current. This electromechanical actuator stops, releases, distributes or combines fluids; and is being extensively used in a number of application areas.

Components of a Solenoid Valve

A Solenoid Valve has parts like a coil of wire (which is the Solenoid), a metal core, electrical connector, bonnet nut, body, etc. These components are necessary for the efficient functioning of the valve. In case a malfunction occurs in any of the parts, the operation of the valve will not be effective.

Hence, it should be checked regularly that all the parts are working in their best possible manner. If not, then replacement(s) might be required to ensure proper working of the valve.

Uses or Areas of Application

These engineered products are used in numerous areas. Some of the uses of a solenoid valve are as follows:

  1. Home Appliances: Be it a dishwasher or a washing machine, these appliances require solenoid valves to work efficiently.
  2. Gas Boilers: Another major use of these valves is in the gas boilers. In boilers, these valves work by controlling the flow of gas towards the burner.
  3. Automatic Irrigation Sprinkler Systems: Not just helping the homeowners of today, but these valves are quite popular in helping the agriculturists as well. The solenoid valves are used in the automatic irrigation sprinkler systems with an automatic controller or regulator.
  4. Dentistry: If you are wondering how these valves are helpful for the dentists, then don’t be amazed! The solenoid valves are used in the dentist chairs so as to regulate the air and water flow.
  5. Water Purifiers: One of the latest uses of Solenoid valves is in the water purifiers or RO water systems that are all the rage at present.
  6. Refrigeration Applications: Solenoid valves are also required in refrigeration applications to commence or restrict the flow in the refrigerant circuit, thereby automatically regulating the fluids in the system.

There are many uses of these excellent valves. However, what is important is that you choose a good supplier of such products, to ensure a long term and hassle free use for years to come. So, do a bit of research online and find a reliable manufacturer offering various types of valves.

ACTUATOR: A fluid-powered or electrically powered device that supplies force and motion to a VALVE CLOSURE MEMBER.

AIR SET: Also SUPPLY PRESSURE REGULATOR. A device used to reduce plant air supply to valve POSITIONERS and other control equipment. Common reduced air supply pressures are 20 and 35 psig.

AIR-TO-CLOSE: An increase in air pressure to the ACTUATOR is required to cause the valve to close. This is another way of saying the valve is Fail Open or Normally Open.

AIR-TO-OPEN: An increase in air pressure to the ACTUATOR is required to cause the valve to open. This is another way of saying the valve is FAIL CLOSED or NORMALLY CLOSED.

ANSI: An abbreviation for the American National Standards Institute.

ANTI-CAVITATION TRIM: A special trim used in CONTROL VALVES to stage the pressure drop through the valve, which will either prevent the CAVITATION from occurring or direct the bubbles that are formed to the center of the flow stream away from the valve BODY and TRIM. This is usually accomplished by causing the fluid to travel along a torturous path or through successively smaller orifices or a combination of both.

API: An abbreviation for the American Petroleum Institute.

ASME: An abbreviation for the American Society of Mechanical Engineers.

ASTM: An abbreviation for the American Society for Testing and Materials.

BALANCED TRIM: A trim arrangement that tends to equalize the pressure above and below the valve plug to minimize the net static and dynamic fluid flow forces acting along the axis of the stem of a GLOBE VALVE. Some regulators also use this design, particularly in high pressure service.
