Patent ID: 8256452

Claim:
A fluid regulating device, comprising: a valve having an inlet, an outlet, and a throat disposed between the inlet and the outlet; an actuator coupled to the valve and comprising a valve disc, the valve disc disposed within the valve and adapted for displacement between a closed position adjacent to the throat, an operating position spaced a first distance away from the throat, and a relief position spaced a second distance away from the throat; and a cartridge disposed in the valve and comprising a cylindrical first portion disposed proximate to the throat, a cylindrical second portion disposed proximate to the actuator, an aperture disposed through a sidewall of the cylindrical first portion, and a conduit portion disposed proximate to the aperture, extending from the first portion and being disposed between the first portion and the outlet of the valve, the first portion of the cartridge having an inner dimension that is sized and configured to slidably receive at least a portion of the valve disc when the valve disc is in the operating position such that the valve disc and the cartridge cooperate to direct a flow of fluid from the throat to the outlet and away from the actuator.
