PRESSURE REDUCING VALVES

WRc plc Listed to BS 6283 : part 4. Pressure reducing valves designed for use in potable water or compressed air systems. NOTE: If any item downstream of the valve cannot withstand the full inlet pressure applied to the valve, adequate pressure relief should be provided upstream of such item. Valves are made principally of bronze or DZR brass, with EPDM seats. They are of spring-loaded EPDM diaphragm type.


Temperature and pressure ratings :
Maximum inlet pressure : 25 bar (367 p.s.i.).
Maximum continuous working temperature : 80 °C
Maximum pressure reduction ratio : 10:1.
Minimum inlet pressure should be at least 1.75 bar (25 p.s.i.) higher than the selected outlet pressure.
P/N 9435 have adjustable outlet pressure in the range 2-6 bar (29.3-88 p.s.i.) and are supplied set at approximately 4 bar (60 p.s.i.). P/N 9241 has range of 0.5-2.5 bar (7-37 p.s.i.) and is supplied set at approximately 1.5 bar (22 p.s.i.). Threads are BSP parallel female inlet and outlet (to BS 2779).
