Construction machinery multiplex valve is a load sensitive proportional reversing multiplex valve with pressure compensation. The working pressure is 420bar, and the flow of single piece is up to 380l/min. It USES the same modular design as a whole to provide a reliable system solution for engineering vehicle manufacturers. The valve body can be combined according to the functional requirements, simple and reliable. It can either be a simple load-sensitive manual multiplex valve or an electrical proportional control valve with unsaturated function independent of load and pump flow.
