General Description
Proportional Relief Valve. Decreasing Pressure With
Increasing Current. For additional information see
Technical Tips on pages PV1-PV6.
Features
Analog Proportional Relief Valve regulates pressure
proportionally to the input solenoid current
Direct acting poppet design
One piece cartridge housing ensures internal
concentricity
Coil: Waterproof, hermetically sealed, requires no
O’Rings; Symmetrical coil can be reversed without
affecting performance.
All external parts zinc plated
