The electric exhaust valve for venting air from the boiler and the electric control valve for feedwater suffer from severe internal leakage. Can grinding the mating surfaces solve this problem?
Thread Content
The electric exhaust valves for air release and the electric control valves for feedwater in our company’s boilers are leaking severely. Can grinding the mating surfaces prevent leaks?
Grinding the mating surface can improve sealing performance, but whether it can completely resolve internal leakage issues requires considering other factors such as seal damage and material aging. It is recommended to first examine the condition of the door frame and seals before deciding on a repair plan. .
It’s highly likely that grinding the sealing surface will not achieve a proper sealing effect. Given the severe leakage you mentioned, there is probably an issue with the fitting angle of the sealing surfaces, and they need to be re-ground.
Thank you very much for your reply. Could you please explain the dressing process? Thank you!
