초록

A fluid pressure regulating valve having a two-stage high and low flow rate control capability combined with a natural-LP gas control pressure changeover uses a spring biased pressure regulating diaphragm controlling a fluid through an orifice defined by a valve seat. A solenoid valve armature is attached to a spring providing the spring bias for the diaphragm and is arranged to be actuated by a selectively energizable solenoid coil. An extension of the armature is captured by a step regulator assembly which is threaded into a valve body containing the r...
