Proportional Relief Valve
Series AP02B2YP 07C, 14C, 21C, 35C
General Description
Proportional Relief Valve. Increasing Pressure With
Increasing Current. For additional information see
Technical Tips on pages PV1-PV5.
Features
•
Analog Proportional Relief Valve regulates pressure
proportionally to the 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.
