Unlike our competitors as part of a standard strip down we take the boiler valve back to our workshop.However valves can be repacked on site if the client prefers. Below i have a brief step by step refurbishment of a typical sight cock done in our workshop.
The valve is back at our worshop and is ready to be stripped. Gaskets are taken off and all valve details are recorded and logged.
Next the valve is stripped and all old packing is removed. The components are placed in a box and sent of for sand blasting and polishing.
Now the valve has returned from cleaning it can be checked for any pitting in the valve and the spindles are replaced if required. Now the valve is ready to be re-packed and assembled.
The valve is now re-built and can be tested using nitrogen. Once it has passed a test, a certificate can be made out, the valve is now ready to be fitted to the boiler.
