Air operated and manual operated regulating valve is in the control system for surface BOP stacks functions in reducing the high oil pressure (21Mpa) in the accumulator to the low pressure (generally 10.5MPa) needed for controlling BOPs. In addition, this valve also undertakes the task of automatic overflow and pressure reduction under a certain operating condition. Therefore, the valve has two functions such as pressure reduction and overflow.
