D05 UNLOADING MODULE
This module allows unloading or venting pump pressure during idle machine cycles. It is mounted between a single solenoid, spring offset directional control valve (NFOA D05 size) and the manifold. When the valve is in the P to A position, this module directs the pump flow back to tank, thus unloading the pump. When the directional control valve is in the P to B position, the B port is blocked and pump flow is directed to other system control valves.
