Pneumatic U-type Diaphragm Valve with Positioner
Donjoy Pneumatic U-type Diaphragm Valve with Positioner(or membrane valves) consists of valve positioner, an actuator and U-type 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 outer environment, specifically use for aseptic processes biopharmaceutical industries. The valve body constructed from Stainless steel 316L, all parts that contact with the medium are mirror polished. Connection End available in tri-clover/clamp, butt weld, thread, flange.
