The 3-position and 4-way rotary valve is one of the main hydraulic components of the control system for surface BOP stacks. The high pressure oil in the accumulator enters each controlled object via this valve; in addition, BOPs are opened or closed by switching this valve.

The 3-position and 4-way rotary valve can realize manual switching and also pneumatic switching by operating the pneumatic rotary valve on the driller's console.

The pneumatic pump is one of the main hydraulic components of the control system for surface BOP stacks. The pneumatic pump uses compressed air as the power source. The pneumatic pump is a device converting air pressure energy into hydraulic energy and can increase pressure up to 40MPa. During remote control, the pneumatic pump mainly acts as auxiliary pump. When a motor doesn’t work, the pump can pressurize the whole system.

Model:	QYB40-120L
Maximum output pressure:	40MPa
Displacement per stoke:	128ml
Air supply pressure:	0.5～1.2Mpa
Compression ratio	60：1
Piston travel	97mm
Air cylinder diameter:	216mm
Hydraulic cylinder diameter:	28mm

The relief valve 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.
