The Blowout Preventer (BOP) Surface Control Unit, commonly referred to as the **Hydraulic Control Unit (HCU)**, is a critical device used to control wellhead BOPs, hydraulic choke valves, and kill valves. It is an indispensable component in drilling and workover operations. The control objects of the unit align with the configuration of surface BOPs. Due to varying control methods, products within the same series exhibit different structural compositions and are available in multiple model specifications. Our company currently manufactures over 50 specifications of surface BOP control units, with control objects ranging from 2 to 15. These units cover all surface BOP models in terms of specifications and functions, meeting conventional usage requirements. Additionally, we can design and customize special control systems according to customer requirements.
