Abstract

Perfections introduced in a pressure regulating valve including a housing having an inlet and outlet, a valve seat in the housing between the inlet and the outlet, and a disc valve located on the outlet side of the seat with its face exposed to the inlet pressure and cooperating with the seat to regulate the flow, characterized by a hermetically sealed bellows (46 or 78) located on the outlet side of the seat (32 or 62) and having a fixed end with relation to said seat and the other end connected to said valve (34 or 80), and means of loading in said bellows that maintain the valve copper seat until the force of the inlet pressure acting on the valve face exceeds of the strength of said means of loading.
