Steam Control and Condensate Drainage for Heat Exchangers
userpages.umbc.eduregulating valves. Failure to install a drip trap will allow condensate to collect in the steam piping ahead of the regulator. As the regulator opens, the mix of condensate and steam passing through the regulator may cause water hammer that can destroy the diaphragms or bellows used to operate the regulator. A steam strainer should also be ...
