This unit is a direct acting, screw in cartridge style, spool type, hydraulic directional logic element, with multi-functional potential when used with other directional pressure or flow control devices.

This valve blocks flow from port 1 to port 2 with a spring bias. It will shift to allow full flow from port 1 to port 2 only when the pressure in port 1 exceeds the cumulative pressure of port 3 plus the bias spring force value. When no pressure is present at port 3, it will allow flow from port 1 to port 2 once the bias spring force is overcome by the pressure in port 1. This is a pilot to close directional logic element.
