KT Hydraulics has completed a contract for Isle of Man Water to replace the guard-valves and associated operating systems at its Clypse reservoir on the island. The previous upstream guard-valves at Clypse had been manually operated from the surface via rod linkages over 50m long. Once the reservoir had been drained and the existing upstream valves and linkages removed by IoM Water Authority contractors, KTH supplied and installed two hydraulically operated guard-valves with actuators plus the required control panel and hand operated hydraulic pump on the surface and all the necessary hydraulic pipework to link the system together. KTH engineers then flushed, tested and commissioned the completed hydraulic system.
