DIRECT ACTING PRESSURE RELIEF VALVES
The direct acting relief valve limits the pressure in a hydraulic circuit.
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. This is limited
by a pack spring with a mechanical stop (only standard screw and nut), which
prevents temporary P closures caused by pressure peaks.
It has a galvanised steel body. The guided ball poppet is in tempered and
ground steel.
