This is a direct-acting, spool-type, proportional, pressure reducing/relieving valve. It is a drop-in, flange mounted cartridge type valve. The coil is an integral part of the valve and is not serviceable. The regulated pressure is inversely proportional to the input electrical current.
When no current is applied to the coil the valve allows free flow from 2 to 1 with the spring chamber constantly drained at port 3. Upon attainment of a predetermined pressure at port 1, the spool shifts to restrict inlet flow from port 2, thereby regulating the pressure at port 1. In this mode the valve will also relieve port 1 to port 3. Increasing current to the coil will decrease the control pressure at port 1 proportionally.
