The control system for surface mounted BOP stacks is essential equipment for the control of BOP stacks, hydraulic chock valves and kill valves in the drilling and workover drilling operations to prevent blowout.
Control system for surface mounted BOP stacks has the below features:
1)Reliable hydraulic system, high efficiency, easy operating measures and convenient repairmen.
2)Accumulator's design can meet the requirement of closing all BOP stacks
3)If an accumulator or a series of accumulators are fails to work, the capacity loss wll not exceed 25% of the total capacity.
1)working pressure :21MPa(3000psi).
