Relief valve
Variants
The valve has a combined function in a single cartridge. It consists of a direct
acting maximum pressure valve and a unidirectional check valve.
The relief valve 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.
The spring in the check valve enables the cartridge to be mounted in any
position.
It has a galvanised steel body. The tapered poppet of the relief valve and the
guided ball poppet are made from tempered and ground steel.
