The Plug and Cage trim design provides the maximum flow capacity for a cage trim choke valve. In the closed position, the plug makes contact with a prepared shoulder in the cage to facilitate positive shut off. Flow is directed into the trim via ports and impinges in the centre of the flow cage. The plug is guided internally in the flow cage controlling the opening of the ports and the flow rate. The flow cage is supported at both ends by the body and bonnet providing a rigid and robust

The External Sleeve type trim uses a flow sleeve moving over the outside of a ported cage to control flow. A metal to metal seat design on the outside of the flow sleeve and out of the high velocity flow assures positive shut off and an extended seat life.

The controlling element (flow sleeve) moves in a lower velocity regime and leads to the high erosion resistance of this trim design. Applications of these chokes include high pressure drops, and fluids with entrained solids such as formation sands.

This trim is furnished in Tungsten Carbide with a equal percentage characteristic.
