How to Choose the Best Diaphragm Valve Diaphragm valves are a type of valve that closes or opens a fluid path by using a flexible membraned called a diaphragm to regulate the pressure in the system. In this article, we'll take a look at how these valves work and what types you might want to consider for your project.
What is a Diaphragm Valve? A diaphragm valve is a mechanical device that allows the passage of fluid or gasses. The end that moves or opens is called the diaphragm and the stationary end is usually shaped like a disk. A pressure differential between the two sides of the valve causes it to open.
How do diaphragm valves work? Most industries require a closed loop system to maintain the pressure in a tank. These systems use a diaphragm valve to regulate the flow of steam, gas or other fluid. A diaphragm valve also eliminates leakage because there is no risk of open communication between the inside and outside of the tank. The pressure differential across the rubber diaphragm creates an airtight seal.
Type of Diaphragms A diaphragm valve is a mechanical valve that uses an increase in pressure to open and close the valve. There are several types of diaphragm valves, including: There are two types of diaphragm valves: Diaphragm-Piston Valve and Floating Piston Valve. The former is designed to be used in applications where flow rates vary while the latter is for constant flow rate applications. A diaphragm valve is limited by the speed of the diaphragm.
Common Diaphragm Valves in Use A diaphragm valve is used to control the flow of fluids in applications where pressure regulation is desired. A common type of valve is the diaphragm valve, which uses a flexible membrane (diaphragm) to divide two chambers. The pressure difference between the two chambers moves the membrane and ensures that fluid flows in one direction only. Diaphragm valves are made up of two sets of components: spool, spring, and diaphragm; and stem, actuator rod, and body (or bonnet).
