PRODUCT DESCRIPTION:
Diaphragm valves get their name from a flexible disc which comes into contact with a seat at the top of the valve body to form a seal. A diaphragm is a flexible, pressure responsive element that transmits force to open, close or control a valve. Diaphragm valves are related to pinch valves, but use an elastomeric diaphragm instead of an elastomeric liner in the valve body, to separate the flow stream from the closure element.
