What is a globe valve and what is it used for Globe valves are linear motion valves and they can be used to start-stop and regulate the fluid flow. Globe valves are mostly used for throttling service and for automatic control. A…

What is a needle valve and what is the purpose of needle valves The needle valve got its name because of its narrow tapered plug and port arrangement. The needle valve is small in size and the control of the fluid flow…

What is a diaphragm valve and what does it do A diaphragm valve is different from other valves, diaphragm valve doesn’t have a valve disc. This valve uses a diaphragm for its opening and closing purpose. This valve is a linear motion…

Describe control valves Control valves are used to control the flow and direction of fluid such as gas, water, steam or chemical compounds. They are controlled so that the load disturbance can be compensated. Control valves are used in gas centrifugal compressors…

Why do we need control valves Control valves are used to control the flow of the liquid, it can regulate the fluid flow when the position of valve plug or disk is changed from the force from actuator to do this the…

What is a valve A valve is a device that can be used to control the flow of the fluid, a valve can regulate, direct or control the flow of fluid. The controlling of the flow is done by opening or closing…

The main difference between pneumatic and mechanical actuators is their working speed. The two systems are so distinct, that one can not replace the other with a drop-in. Each one has its own intrinsic benefits and disadvantages: Advantages of Pneumatic actuators: The…

The actuator is an essential part of the control valve, which drives the control valve stem. In order to select an appropriate control valve, an engineer should know about the varieties in valve actuators and its specifications. The actuator for a valve…

What is cavitation in control valve? Cavitation is phenomenon caused to boil or bubble formation (which results in tremendous sound at pipeline joints) due to decrease in pressure rather than by increasing temperature. Cavitation happens at a junction where there is an…

“Open/closed lock valve or open / closed valve car seal” is not a form of valve. It’s a valve’s “health.” A lock or a Car-Seal can be applied to any door. These apps would be known as an “add-on after-marker.” A locking…
