External Sleeve Choke Valve-Cage Choke Valve

External Sleeve Choke Valve is widely used on the well and often equipped on the choke manifold, kill manifold, x-mas tree, pipe line for oil production and injection, well drilling, well testing operation. Especially for the severe working condition. The external sleeve type trim uses a flow sleeve moving over the outside of a ported cage to control flow. Designed for high pressure drops and severe erosive flow with sand combination Designed especially for high pressure drops and severe erosive flow with sand combination.

These choke Valves are designed, manufactured in accordance with API Spec. 6A and easy for operation and maintenance and widely used in many oilfields. And earned a high reputation.
