PRESSURE RELIEF VALVES
Variants
The pilot-operated relief valve limits the pressure in the hydraulic circuit.
Slight leakage is tolerated for this type of valve.
It raises the safety level by making it impossible for the plant operators to set
a higher pressure rating, than that specified in the catalogue. It has a pack
spring with a mechanical stop.
It has a galvanised steel body. The tapered pilot poppet and cylindrical main
plunger are made from tempered and ground steel.
