The pressure valve group adopts a combination of plate valve and two-way insert valve to avoid the difficulty of maintaining the two-way insert valve and retain the strong fluidity advantage.
The valve is equipped with dual pump oil inlet and secondary pressure regulation functions, with a maximum flow rate of up to 400 L/min and a pressure of up to 315 bar. When low flow rate operation is required, single pump operation can also be used, and excess energy can be unloaded to achieve the purpose of energy saving and emission reduction.
In order to achieve the accuracy requirement of the insertion hole, composite forming tools are used for valve block processing, and the valve block is inspected by an endoscope after deburring to ensure quality control. The valve block surface treatment adopts zinc-nickel alloy treatment, and the salt spray test can reach 720 hours with a protection rating of S.
The product has been experimentally verified and has been stably operated on the die-casting machine for 5 years, and is deeply loved by users.
