Butterfly Valve Premature Failure
« on: June 01, 2010, 06:21:35 AM »
I would like to ask anyone's technical assistance regarding our (Apollo) butterfly valves which is failing prematurely. The seat was found bulged and could no longer provide tight closing. Operations guys are has always been experiencing difficulty when closing this valve. The service is compressed air with maximum temperature of up to 60 degrees Celsius only. The seat material is Buna-N. What could have cause this failure?
