When steam is used for heating, control Valve and temperature control valves are often used. May the temperature control trap be used in place of these control valves?
There is a crucial difference between the kind of temperature control provided by a control valve or a temperature control valve and that provided by a temperature control trap. Control valves and temperature control valves use the product temperature as their reference, while temperature control traps reference the temperature of the trap interior. Therefore, a temperature control trap cannot be used as a substitute for a control valve or temperature control valve in a typical heating situation.
