FLOAT AND THERMOSTATIC TRAP

a reference to a device in a steam heating system that regulates the flow of condensed steam by the action of a float. The function of a steam trap is to discharge condensate from steam piping or steam heating equipment without permitting live steam to escape. In a float and thermostatic trap, when the condensed steam (or water) in the trap builds up to a high enough level, the float rises and holds a valve open allowing the condensed steam to flow out. When the temperature in the trap drops below that of the steam temperature, the thermostat operates to let any air that may have accumulated pass out into a drain. This device is suitable for hotwater heaters and any equipment having high steam capacity.
