1、This series of back-pressure valve, is a twisted view of the current deep-bed-type pressure balance valve to prevent the use of self-respect to land when moving slow, noisy, and the back-pressure control of injection molding machine is not accurate, pressure loss is too large to be studied and various other shortcomings of the improvements in Cheng, the most suitable for deep-twist-type press beds, injection molding machines, a variety of other needs and generate back pressure to prevent the landing weight of the hydraulic device
2、Installation dimensions in line with ISO 6264 standards.
