JYSQ21-25 Пневматический/Ручной Pressure Regulating Клапан | ПВО Control Клапан

The purpose of the manual decompression relief valve in the surface ПВО control device is to reduce the high pressure fluid (21 MPa) in the accumulator to the lower pressure required to control the ПВО (usually 10.5 MPa). In addition, under certain conditions, the valve also has the function of automatic overflow and pressure reduction, so the method can be used for both oil and tooth overflow.
