Choke Valves

Master Flo’s choke valves and actuation are proven worldwide in the most demanding surface and subsea applications, with over 100.000 units delivered all over the world.

Master Flo’s superior valve design, expertise in custom trim and material selection for your application, life-of-field flow management expertise and commitment to service, are relied on to provide critical flow control in all service types.

We use external sleeve over ported cage trim, which is the surface and subsea industry standard, particularly for high-pressure, large-pressure drop, and severe service applications.

The external sleeve over ported cage design delivers superior performance by impinging flow on itself in the center of the cage, dissipating the throttling energy.

The impinged flow is directed upward, into the trim and away from the outlet, which further reduces the throttling energy and contains residual wear to the hardened trim components.

As a result, the throttling energy is dissipated before it enters the outlet bore. This protects the outlet wall from erosion that high velocity flow can cause.
Further protection from erosion is provided by the retaining sleeve, which isolates the main body bore from the incoming flow.
