JYSQ21-25 Pneumatic/Manual Pressure Regulating Valve | BOP Control Valve
Description
The purpose of the manual decompression relief valve in the surface BOP control device is to reduce the high pressure fluid (21 MPa) in the accumulator to the lower pressure required to control the BOP (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.
