PROPORTIONAL RELIEF
Increasing Pressure with
Increasing Current
■ Pilot operated spool-type design fits industry common cavity (10-2).
■ Relieving pressure output is proportional to DC current input.
■ Precise setting of factory preset pressure in energized mode.
■ One piece cartridge housing ensures internal concentricity.
■ Coil: Waterproof, hermetically sealed, requires no O’Rings;
Symmetrical coil can be reversed without affecting performance.
OPERATION
This valve is a proportional pilot operated relief valve giving minimum
relief pressure with zero input current to the coil. Increasing current to
the coil increases the pilot relief setting proportionally allowing full flow
relief proportional to the input current from nose to side.
