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.

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.

Crankshaft Plunger Pumps

The crankshaft plunger pump is a triple plunger pump driven by crankshaft connecting rod and uses valve distributing mode. Therefore, the crankshaft plunger pump has such advantages as simple structure, convenient maintenance and strong resistance to pollution and is applicable to site operating conditions. The crankshaft plunger pump is used for the system using hydraulic oil as medium.

The control system for surface BOP stacks (hereafter abbreviated to hydraulic control system) is very important equipment which controls BOP stacks and gate valves controlled by hydraulic pressure especially in drilling and workover operations. It is necessary to accurately operate and maintain the hydraulic control system. The hydraulic control system manufactured by Shenkai Company can be divided into 3 types: 
1.Directly manually operated FK series hydraulic control system 
The hydraulic control system not fitted with a driller’s console is applicable to drilling or workover operations and is simple and portable. The hydraulic control system can be fitted with a mechanical anti-lifting device (see the operation manual for the anti-lifting device). 
2.Pneumatic liquid type FKQ hydraulic control system 
This hydraulic control system is fitted with a driller's console or an auxiliary driller's console (optional). Alarm type and non-alarm type driller's console and auxiliary driller's console can be installed as demanded by users. Air pipe bundles are used to connect the remote console with the driller’s console and the remote console with the auxiliary driller's console for the pneumatic liquid type hydraulic control system, so that the hydraulic control system can be remotely controlled on the driller's console and the purpose of opening and closing BOPs can be achieved. This hydraulic control system is generally used in drilling operations. The hydraulic control system can be fitted with a mechanical anti-lifting device (see the operation manual for the anti-lifting device). 
3.Electrical and pneumatic liquid type FKDQ hydraulic control system 
The remote console is fitted with a driller's console or an auxiliary driller's console (optional). In addition, explosion-proof driller's console and auxiliary driller's console applicable to hazardous and explosive gas environment area I or II can be installed as demanded by users. 
This hydraulic control system is Siemens PLC controlled and runs stably and reliably. Fire-resistant four-core ship cables and standard Profibus communication connection are used to connect the remote console with the driller’s console and the remote console with the auxiliary driller's console for the hydraulic control system. In addition, a touch screen driller’s console and a PN-T remote console status self-recording module can be installed as demanded by users. The hydraulic control system can be fitted with an electrical or mechanical anti-lifting device (see the operation manual for the anti-lifting device).
