ABSTRACT:
A main hydraulically operated valve body has a valve element therein which is biased closed when inlet pressure is applied to both sides thereof and is moved openward when inlet pressure is variably exhausted from its outlet side through a pilot valve having a body rigidly mounted on a casing enclosing a meter actuated preset mechanism. The pilot valve body has a single valve element therein connected to the preset mechanism for preventing and controlling exhaustion of inlet pressure therethrough and conduit connects the main and pilot valve bodies.
