Caleffi - 536083A 109 HP (sweat, high range) High performance piston type pressure reducing valve for high rise buildings and other applications where high pressures are present and require staged pressure control. The 536A series carries out the first stage pressure reduction in a two valve series where the pressure ratio between the inlet and outlet would be too high for a single pressure reducing valve to control.
