Valve control and/or lubrication system

A system for operating and/or lubricating a plurality of valves which are mounted on a number of Christmas trees, each valve comprising a hydraulic actuator which is operated by hydraulic pressure from a hydraulic pressure source and/or 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 comprising:

• a plurality of control units, each of which is associated with a respective valve, each control unit comprising 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 further comprising a hydraulic port and a lubricant port;
• a hydraulic conduit which is connected between the hydraulic port and the hydraulic actuator and a lubricant conduit which is connected between the lubricant port and the lubricant inlet;
• each control unit further comprising a hydraulic activation means for selectively connecting the hydraulic pressure line to the hydraulic port and a lubricant activation means for selectively connecting the lubricant line to the lubricant port;
• whereby each control unit is operable to selectively connect the hydraulic pressure source to the hydraulic actuator to thereby operate the valve and to selectively connect the lubricant source to the lubricant inlet to thereby communicate lubricant into the interior portion of the valve.
