DEMA’s special purpose valves are “manifolding” diaphragm valves constructed of 30% glass filled nylon or PVC that can be joined to form a manifold without bushings or connectors. Applications for 466P, 481P, and 482.2 include: Water, air, light oil, noncorrosive and non-explosive liquids. EPDM seal is standard, Viton is available on request.
