ABSTRACT:
Valve apparatus including a regulating valve controlling fluid flow through a duct and positionable to produce a regulated downstream pressure from a normally relatively higher upstream pressure. A pilot valve enables a relatively reduced fluid pressure to be used on and in connection with a regulating valve operator. The pilot valve responds to inlet pressure and enables sequential operating steps according to which, in part, the regulating valve moves to a fully open position upon inlet or upstream pressure dropping to a predetermined low value and moves to a fully closed position upon inlet or upstream pressure dropping below the predetermined low value.
