Function
- Motor driven, Cartridge-style, Hydraulic pressure reducing/relieving valve with internal spring chamber drain, designed to act as a pressure-regulating device for secondary circuits.
Operation
- The PR11A allows flow to pass bidirectionally from 2-1 with the spring chamber constantly drained at 3.
- Once pressure reaches a pre-determined pressure at port 1, the cartridge shifts to restrict input flow at 2, thereby regulating pressure at 1. In this mode the valve will also relieve 1 to 3.
