Abstract:
1. A process fluid regulator comprising: a regulator body having a fluid inlet and a fluid outlet connected by a fluid flow path; a control element disposed within the fluid flow path, the control element cooperating with a seat to control a flow of process fluid through the regulator body; an actuator attached to the regulator body, the actuator having an upper housing and a lower housing, a diaphragm disposed within the actuator and dividing the actuator into an upper chamber and a lower chamber; an actuator stem connected to the diaphragm and to the control element; and a high pressure bleed valve attached to the lower chamber, the high pressure bleed valve forming a fluid passageway with the lower chamber to vent residual gas from the lower chamber, wherein the high pressure bleed valve includes an inlet tap plug having a central bore and a transverse bore, and a vent screw at least partially disposed on the central bore, a vent tube at least partially disposed in one end of the transverse bore, and a back stop screw at least partially disposed in another end of the transverse bore, the vent screw including a plug at one end, the plug cooperating with a shoulder formed in the central bore to control fluid flow through the central bore.
