China Manual Pneumatic Pressure Regulating Valve Jys21-25&Jysq21-25 Overflow Valve Pressure Regulator Relief Valve

Manual Pressure Regulating Valve
1 Overview
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.
Hand pneumatic relief valve
1 Overview
Hand Pneumatic Relief Relief Valves (Pressure Regulating Valves) function in the surface BOP control device to control the pressure of the annular BOP, reducing the high pressure fluid (21Mpa) in the accumulator to a lower pressure (usually It is 10.5Mpa). In addition, the valve can also automatically overflow, is a relief valve.
