ABSTRACT:
A steam trap including a buoyant float member is equipped with a valve seat assembly which is closed by abutment of the float with a valve seat portion surrounding the flow orifice. The assembly is formed with a float abutment member made of carbide located adjacent the valve seat surface on the outer periphery thereof and located to serve as a contact point for the float member and to define a fulcrum about which the float may pivot when moving into and out of contact with the valve seat surface. The material of the float abutment member ensures a longer service life and a more secure closure of the flow orifice.
