External Sleeve

Similar features to the plug & cage however has a reduced capacity.
Used in low capacity/high pressure drop applications with erosive service.
The externally guided flow sleeve controls the opening and rate of flow.
Our trim has been designed specifically for severe erosive service in combination with the high pressure drops and high sand concentrations
The flow is directed upward away from the outlet, impinges on itself in the center of the flow cage which in turn isolates the body bore from incoming turbulent flow hence eliminating the body wear.
The seating is achieved through an isolated sealing element contact on a seat outside the flow cage. Keeping the seat surface away from the high velocity flow protects the seat from throttling wear and the seat integrity is maintained.
