Recently, we plant the point of a small problem, barrier pipe production plant, the plant’s maintenance personnel is a one of the checks did not check out the pipeline is a pipeline which blocked. No way to please professional maintenance man, the maintenance man came to check it out but no one will be the failure of the valve. Originally this point issues, maintenance workers suggested that we change into Triple offset butterfly valve. Said to be more durable Triple offset butterfly valve, said plant like ours can only use Triple offset butterfly valve, if the use of other valves often broken. We also listened to the views of the public service, all replaced by Triple offset butterfly valve.
