Pneumatic Diaphragm Valve
Pneumatic Sanitary diaphragm Valve (or membrane valves) consists of an actuator and valve body with two or more ports, an elastomeric diaphragm, and a “weir or saddle” or seat upon which the diaphragm closes the valve. It provides a body seal and a seat seal. There is no path contact to the outside environment, specifically for aseptic processes biopharmaceutical industries. The valve body constructed from Stainless steel 316L with the manual or pneumatic operation, automated with a valve positioner. Connection End available in tri-clover/clamp, butt weld or thread.
