ABSTRACT:
A valve housing has an inlet bore configured for connection to a fluid supply pipe an outlet bore configured for connection to a fluid distribution pipe. A valve assembly mounted in the housing controls fluid flow between the inlet bore and the outlet bore. A valve seat is mounted in the housing, and a valve stem guide having a plurality of passages for permitting fluid flow therethrough are mounted in the housing. A hollow bolt shaft extends into the housing. A valve stem extends into the hollow bolt and through the valve stem guide and the valve seat. The valve stem guide and the hollow bolt cooperate to hold the valve stem in predetermined alignment relative to the fluid transmission bore. A plunger is mounted to the valve stem upstream from the valve seat. A stop is mounted on the valve stem to limit motion of the valve stem such that the first end of the valve stem is retained within the hollow portion of the adjusting bolt. A spring is retained between the end of the bolt shaft and the stop to bias the plunger away from the valve seat. The spring is arranged such that a predetermined fluid flow rate produces a force on the plunger sufficient to move it into contact with the valve seat and thereby shut off the fluid flow.
