Diaphragm valve is a type of valve that uses a flexible diaphragm to regulate the flow of fluids.When the valve is open, the diaphragm is lifted off the seat, allowing fluid to flow through the valve. When the valve is closed, the diaphragm is pressed against the seat, cutting off the flow of fluid.easy to clean, have no dead spaces where fluids can accumulate, and can be used in applications where contamination must be avoided.
Diaphragm valves are also used in applications where the fluid being handled is corrosive or abrasive.

1/4 inch VCR 316L EP diaphragm valve with a low pressure rating of 150psi is a reliable and precise valve that is suitable for use in a variety of low-pressure applications, particularly those in the semiconductor and biopharmaceutical industries.
