The condensation steam trap device includes a housing having a passage through the wall, which provides for fluid flow between the interior and exterior of the housing. The passage has a valve seat and carries a valve for engagement with the seat.WATER POWER CONTROL VALVE A valve-actuating, temperature-sensitive element is disposed within the housing and has a connection with the valve for controlling the opening and closing thereof in response to changes in temperature of the element.Bellow Seal Valve The element is a bimetallic band or strip of curved or part-cylindrical shape. A nozzle or inlet pipe projects through another portion of the housing wall as well as through a clearance opening in the strip, Water Control valves the axis of the pipe and the discharge end thereof being directed against the inner surface of the strip substantially tagentially thereof. Condensate flowing through such pipe thus impinges a substantial area of the curved bimetallic strip causing the latter to move in response to a temperature change to a greater extent than would be true by directing such flow radially against the exterior of the strip. Upon actuation of the strip in response to temperature changes the valve in the aforesaid passage is also moved thereby controlling the degree of opening and closing thereof.
