摘要： A balanced trim 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, the movable valve plug interacting with the valve seat to selectively open or close the fluid passageway. A cage is disposed in the fluid passageway, the cage surrounding the valve plug, and the cage including at least one a balancing passage that fluidly connects the fluid passageway with a balancing chamber.

摘要： A valve assembly includes a first body portion, a second body portion secured to the first body portion, and a cage positioned between the first body portion and the second body portion. The cage has a generally cylindrical body, a bore formed longitudinally through the body, a top surface, an opposing bottom surface, an exterior surface, an opposing interior surface, and an integral, unitary annular flange extending from the exterior surface and around a perimeter of the cage. The annular flange includes a first surface configured to engage the first body portion to form a seal between the cage and the first body portion and a second surface configured to engage the second body portion to form a seal between the cage and the second body portion.

摘要： An anti-cavitation cage for a valve assembly. The anti-cavitation cage includes a body having a plurality of slots, a first end, and a second end. At least one slot of the plurality of slots includes an inside surface having a lattice structure. The lattice structure is one of uniform in grade through the at least one slot or a graded type of lattice structure varying in density from a first portion to a second portion. The anti-cavitation cage having these features is a single component.
