PresCal™ HP (low range)
Description:
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 536 Series carries out the first stage pressure reduction in a two valve series where the pressure ratio between the inlet and the outlet would be too high for a single pressure reducing valve to control.
Max working pressure: 360 psi (24.8 bar)
Max working temperature: 180°F (80°C)
Pressure setting range: 10 - 90 psi (0.7 - 6.2 bar)
