Abstract
A thermostatic control valve for a one-pipe steam system formed by the combination of a conventional vent valve and a temperature controlled valve for closing the flow passage into the vent valve at a pre-set ambient temperature. The temperature controlled valve is preferably in the form of a self-contained temperature responsive valve having a valve chamber with an inlet connection to a radiator of a one-pipe steam system and an outlet leading into the vent valve. A valve seat is provided between the inlet and the outlet and a valve member cooperates with the seat and is movably actuated through an arrangement controlled by a heat expansible fluid which may, if desired, be positioned in a remote bulb.
