The plug and cage trim uses a solid plug with a pressure balancing holes moving inside a ported cage to control flow.
This design provides the maximum flow capacity for a cage trim choke valve.
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 pressure balance sleeve providing a rigid and robust design.
In-line straight pattern body also available.
Centre to face distance can be manufactured as per customer requirement. However JVS has standard dimensions as per best industry practice.
4 x 4 control choke trim
Flow is directed through ports into the centre of the trim where it impinges on flow from the opposite port.
4 diametrically opposite ports will provide the highest wear resistance in a 'cage' type flow trim.
4 small ports in the lower section provide fine control at low openings while 4 larger ports provide capacity for higher flows.
