Manual Diaphragm

Manual Diaphragm Valve: A device, also called a membrane valve, comprised of a valve body with two or more ports, a diaphragm, and a "saddle" or seat upon which the diaphragm closes the valve. Diaphragm valves are frequently used by the bio-pharmaceutical industry by using compliant materials that can withstand sanitizing and sterilizing methods. There are two types of diaphragm valves: the saddle type and the seat type. The saddle-type valve has two ports in line with each other on the opposite sides of the valve. The seat-type has the in and out ports located at 90 degrees from one another. The saddle type is common in process applications. The seat-type is commonly used as a tank bottom valve.
