Patent ID: 10982808

Abstract:
A system for operating and/or lubricating a plurality of valves which are mounted on a number of christmas trees and which each include a hydraulic actuator which is operated by hydraulic pressure from a hydraulic pressure source and a lubricant inlet which is connected to an interior portion of the valve that is configured to receive a lubricant from a lubricant source. 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.
