JYS-21.25 manual pressure regulating valve product introduction:
The manual pressure regulating valve JYS21-25 introduces that the function of the manual pressure relief valve in the ground BOP control device is to reduce the high pressure oil (21MPa/3000psi) in the accumulator to the lower pressure (usually 10.5MPa/1500psi) required to control the BOP. In addition, under certain conditions, the valve also has the function of automatic overflow and pressure reduction, so the valve has two functions of pressure reduction and overflow.
