Abstract
A thermally controlled steam trap valve with a housing having an internal chamber which is connected to the inlet and also including an outlet. There is a valve seat disposed in the housing for covering the outlet and a valve shaft which has a spherically shaped valve member mounted on the shaft for closing off the valve seat in response to a bimetallic element. Guide pin elements in the form of bushings are disposed in the housing at opposite ends of the shaft and have diametrical clearances which are coordinates with the axial spaces between the center point of the spherical valve member and the points of contact with the shaft with the guide bushings. In another embodiment the valve seat has a yoke with ribs extending over the bimetallic element. The valve member has radial guide shoulders which include openings for the discharge which cooperate with the inner wall of one of the bushings.
