Pressure Reducing Valves
Pressure reducing valves hold high-pressure steam or fluids steady at the required downstream pressure while preventing overpressure. Direct-acting types are simple and dependable; pilot-operated types suit high flows and tighter accuracy, protecting downstream equipment.
Spirax Sarco 25P Pilot-Operated Pressure Reducing Valve DN15-DN150 SG/CI/CS Flanged Connection
Spirax Sarco 25P is a self-acting, pilot-operated pressure reducing valve for stable downstream steam pressure control across sizes ½" - 5".
Spirax Sarco DP27/DP27LC Pilot-Operated Diaphragm Pressure-Reducing Valve, Flanged
Spirax Sarco DP27 series pilot-operated pressure-reducing valves feature ductile iron valve bodies for steam and compressed-air systems. DP27E includes a solenoid valve assembly for remote switching or timed control. These valves must not be used for oxygen service.
