US Patent 11402064 Valve control and/or lubrication system

A system for operating and/or lubricating a plurality of valves mounted on a number of christmas trees, each valve including a hydraulic actuator operated by hydraulic pressure from a hydraulic pressure source and a lubricant inlet connected to an interior portion of the valve. The system includes a plurality of control units, each of which is associated with a respective valve and each of which has at least one of a hydraulic pressure line which is connectable to the hydraulic pressure source and a lubricant line which is connectable to the lubricant source. Each control unit is operable to selectively connect the hydraulic pressure source to the hydraulic actuator to thereby operate the valve and/or to selectively connect the lubricant source to the lubricant inlet to thereby communicate lubricant into the interior portion of the valve.
