ABSTRACT:
For use with a remotely actuated fluid supply valve, an internally balanced pressure regulating module is provided for regulating the pressure downstream of the valve by modulating the rate at which fluid is bled from a closure chamber of the valve in response to downstream pressure. The module includes a flow restricting member arranged at the open end of a cylinder and having a first surface facing the open end of the cylinder and a second surface facing outwardly of the cylinder and exposed to downstream pressure. The flow restricting member is secured to a piston in the cylinder which is resiliently biased toward the open end of the cylinder, and the downstream pressure acting on the second surface urges the first surface against the force of the biasing means, into a flow restricting relationship with the open end of the cylinder.
