ABSTRACT:
A self-powered servo-actuated backpressure regulating valve including a valve housing (1) having an inlet port (2) and an outlet port (3). A valve plate (4) is disposed in the housing (1) and supported by an evacuated chamber (12) defined by a bellows (10) so as to be movable toward and away from a valve seat (15) of the inlet port (2) fluid pressure acting on the valve plate (4) is controlled by a valve assembly including a valve plate (32) supported in a housing portion (51) of a fixed support (50) by a bellows (30) defining an evacuated chamber (35). The valve plate (32) is exposed to pressure of the fluid in the inlet port (2) by way of an opening (54) with the pressure causing a displacement of the valve plate (32). A bellows (20) supports the valve plate (4) relative to the valve assembly so as to permit movement of the valve plate (4 ) relative to the valve seat (15).
