Armstrong precision burnished stainless steel pistons provide long-term operation, and ensures actuation even after many years without operation. The piston slides without rotating between the two valve sealing rings, preventing dirt from damaging the surfaces.

Armstrong Piston Valves are ideal for saturated and superheated steam, and hot water applications.
