The function of the hand-pneumatic pressure reducing and overflow valve (pressure regulating valve) in the ground BOP control device is to control the pressure of the annular blowout preventer and reduce the high pressure oil (21Mpa) in the accumulator to a lower pressure (usually It is 10.5Mpa). In addition, the valve can also automatically overflow, is a pressure relief valve.
