ABSTRACT:
A pressure regulator that includes a regulator body having a main bore that has a plurality of progressively reduced diameter bore portions in one axial direction, inlet and outlet ports and a vent passage opening to the main bore, a valve assembly resiliently retained in a closed condition to block fluid flow between the inlet and outlet ports, sensor mechanism in the main bore between a main chamber and the dome chamber of a dome threaded on the body that is axially movable by spring pressure and reference pressure applied through a reference port in the dome toward the valve assembly, and a ball connector between the sensor mechanism and valve assembly that blocks fluid flow from the main chamber to vent bores in the sensor mechanism that open to the vent passage and operates the valve assembly to an open condition when the outlet pressure is more than a preselected value above the reference pressure, permits fluid passage from the main chamber to the vent bores and the valve assembly to block flow from the inlet port to the main chamber when the outlet-reference pressure differential is below a preselected value, and to block fluid flow from the main chamber to the vent bores and permit the valve assembly to close when the outlet-reference pressure differential is a preselected value and there is no outlet pressure flow. Tungsten carbide seats are provided in each of the valve assembly and the sensor bores.
