Load Sensing Pressure Compensation Multi-Way Valve Technical Introduction

The invention of load sensing pressure compensation multi-way valve is a product of the development of modern hydraulic technology. The invention is a stackable modern multi-channel control element with load sensing pressure compensation. By comparing the sensing slippery (compensating slippery) pressure difference between the upper and lower cavity ΔP keep constant principle, stepless adjustment of work flow. In changing load conditions, choose any point of travel, have achieved a constant flow control, and with pressure compensation. In the simultaneous operation of multiple valves with different loads, to achieve different traffic and different load pressures independent of each other's synchronization work. Reduce unnecessary power loss, to achieve full-power hydraulic system soft and smooth control. A unique pressure compensation and low pressure relief mechanism to ensure the components of the pressure compensation and low pressure relief function, while reducing the pressure loss to achieve the purpose of saving energy. Varieties have been developed to meet the traveling machinery at 25Mpa pressure 40-300L / min flow range of modern multi-way valve design needs. This element can be used for dosing pumps (open loop systems) or variable displacement pumps (closed loop systems). All seals adopt German "zero leakage" seal structure and seals. Control methods are manual, hydraulic control, manual pneumatic dual control, manual hydraulic double control. Can be any combination within 10 combined. Therefore, to meet the various types of walking hydraulic machinery into the advanced hydraulic components of the design requirements. 1.5SP08GQ load sensing multi-way valve (16T ~ 25T truck crane) Take 16-25T crane as an example. The 5SP08GQ load sensing multi-way valve is an integrated design oil line consisting of DP08 and D08 valves. And to ensure that the lifting of the load-sensing control conditions and to ensure the luffing; slewing; telescopic conditions of reliability. At the same time to achieve a dual pump and three pump a valve system. And the rotating film has a two-way buffer function, to ensure a stable work slewing mechanism. The overall use of tandem oil, to ensure safe and reliable operation. 2.4SDP08GQ load sensing multi-way valve (8T ~ 16T truck crane) 4SDP08GQ load sensing multi-way valve is a patented product developed for 8-16T truck crane. Maintains load sensing and dual pump confluence. At the same time with the rotary buffer function. And all valves are all common. You can also use 4SDP0804GQ double through the complex program to reduce the size of the valve and reduce its manufacturing costs. 3. DP08G-type multi-valve can demonstrate DP08G-type multi-way slide valve function is complete, to meet the design requirements of the system of mobile machinery. Practical hydraulic excavators; loaders; Pipelayer hydraulic open-loop and closed-loop system.Control Valve, Flow Control Valve, Hydraulic Control Valve, Proportional Directional Control Valve
