Abstract
A pressure regulator includes a housing assembly defining a fluid flow path from an inlet end to an outlet end; a plunger having a tubular plunger body supported within the housing assembly for linear movement toward and away from a valve seat in response to fluid pressure at the outlet end. A sleeve is supported within the housing assembly and is engageable with the tubular plunger body, and an actuator collar is supported externally of the housing assembly and operatively attached to the sleeve such that rotation of the actuator collar in one direction from an open position to a closed position produces linear movement of the tubular plunger body, independent of the pressure at the outlet end, into engagement with the valve seat to thereby shut off the flow path within the regulator.
