General Introduction
BOP Control Unit (Hereinafter referred to as hydraulic control unit) is a necessary equipment for controlling wellhead BOP,Hydraulic choke & kill valve, and drilling & workover operation.
Â
Two types of BOP Control Units are offered by us: One is pneumatic control hydraulic device .The hydraulic control device can be remote controlled with driller's console, to achieve the purpose of switching the BOP, which is commonly used in drilling operation; The other one is manual operation, which is suitable for drilling or work-over operation.
