Abstract:
A pressure regulator includes a valve body having a fluid inlet and a fluid outlet connected by a fluid passageway. An orifice is disposed between the fluid inlet and the fluid outlet. A valve seat is disposed within the fluid passageway. A movable valve plug is disposed within the fluid passageway, and the valve plug interacts with the valve seat to selectively open or close the fluid passageway. A cage is disposed in the fluid passageway, the cage surrounds the valve plug, and the cage includes a mechanical stop that limits movement of the valve plug within the cage away from the valve seat.

Claim (Index 17):
A method of removing a trim assembly from a pressure regulator, the method comprising:\n removing a bonnet from a pressure regulator; pulling on a valve stem that is connected to a valve plug to move the valve plug in relation to a cage until the valve plug engages a mechanical stop on the cage; and continuing to pull on the valve stem until the valve plug and the cage are extracted from a valve body as a unit; and forming the mechanical stop by an internal ring having a smaller diameter than a largest diameter of the valve plug; wherein the cage includes a first region having a first diameter and a second region having a second diameter, the first diameter being larger than the second diameter and both the first and second diameters being larger than the internal ring diameter; and locating the first region farther from a valve seat than the second region.
