Abstract
A three-way valve assembly, including a valve body having a fluid flow path and a valve member movable in the fluid flow path between a supply port and a work port, and between a load sense passage and a pressure relief port. The valve member may move between a first position and a second position for controlling flow and regulating fluid pressure differences sensed in the flow path; and for limiting fluid pressure in the flow path to a predetermined pressure level set by a pilot-operated pressure limiter valve when the valve member is in the second position. The valve member may move between the second position and a third position to open the flow path from the load sense passage to the pressure relief port for relieving fluid pressure in the flow path when the fluid pressure from an over-loaded actuator exceeds the predetermined pressure level set by the pressure limiter valve.
