Valve Redesign Promises Good Results
Following disappointing test-rig results with the original bought-in valves, Graham Sykes has completely re-designed the operation system and manufactured custom design main operating valves.
Graham explained "The original ball valves were unable to withstand the pressure temperature of the super-heated water and although they opened on the test-rig, they didn't always shut. The new valves use a completely different concept incorporating bespoke poppet valves, operated by compressed nitrogen. Initial tests using compressed air look very favourable."
The set-back with the original valves has set the project back almost 12 months.
