The integrated modular design of the multi-way valve provides a reliable system solution for engineering vehicle manufacturers. According to the functional requirements of the user to carry out different combinations of valve body, simple and reliable. Can be either a simple load sensitive multi-way valve manually, and can be has nothing to do with the load and the pump flow has nothing to do with the function of unsaturated electric proportional hydraulic multi-way valve, hydraulic Li Gong net of person of outstanding ability of senior consultant, at present our country do most multi-way valve hydraulic engineer is given priority to with application design, system design and development for the valve itself needs to be improved.
Generally, the working valve plate is configured in groups, and the inlet valve block is equipped with a three-way pressure compensation bypass overflow valve (logic element, when the multi-channel valve stops operation and all valves are in the middle position, the valve is used to compensate the pressure (6-·12BAR) bypass main oil flow; When a certain valve work, the valve under the action of load pressure side opening reduced, according to the load pressure to provide the required flow. The load sensing shuttle valve transmits the load pressure of each working valve piece to the pressure compensation bypass overflow valve of the inlet valve block.
Two-way pressure compensation constant difference pressure reducing valve: when several pieces of valve work at the same time, the load pressure to the spring side of the valve. At this point, through the valve center of negative feedback, to automatically adjust the pressure difference at both ends of the throttle port, so that it basically remains unchanged. Under its action, the flow rate of each valve remains constant and is not affected by the change of load.
