Angle Thermostatic Radiator Steam Traps

Angle Thermostatic Radiator Steam Traps, in a trap which is cold, or which is full of condensate below the boiling point, the Sterlco® thermostat remains compressed because of its internal vacuum. The trap is open and condensate flows out or  whenever steam strikes the bellows, the water inside the thermostat starts to vaporize or boil. As soon as the steam pressure inside the thermostat becomes almost equal to the steam pressure surrounding the thermostat, the spring action of the bellows causes it to extend itself and close the trap. Since the thermostat is filled with pure water, the relationship of inside and outside pressures is always the same. This trap will always pass condensate and hold back steam in spite of any variations in steam pressure. If the thermostat is damaged, the vacuum inside will be lost and the trap will remain closed whether it is hot or cold. The location of the trouble will be easy to find because the radiator will be cold. Meanwhile, no steam is wasted.
