Description
The Forbes Marshall Pilot Operated Pressure Reducing Valve, FMPRV53, is a pilot operated cast steel pressure reducing valve suitable for steam or compressed air.
Sizes and Pipe Connections
DN 15, 20, 40, 50 and 80
Flanged to BS table – J and K*
ANSI 300 and 600
DIN - PN 25* and 40
Note : *DN 80 has these flanges only.
Available with IBR certificate.
Flange thickness as per Dimension Table.
Operating Range
Pressure Sensing Pipe
The FMPRV53 valve controls the downstream pressure by sensing the downstream pressure through an external sensing pipe taken from downstream to the pilot valve chamber (10). Fitting of this external pressure sensing pipe is described in the user manual.
If the external sensing pipe is not provided then the valve controls by internal pressure sensing pipe (19). However the capacity in this case will be reduced.
Dimensions (approx.) mm and kg
General tolerance: up to ±4mm
