GFLO Choke Control Valve

GFLO Choke Control Valve

GFLO Choke Valves offer superior performance and erosion protection in high pressure drop liquid, gas, and 2-phase flow applications. Available in either manual production choke configuration, or actuated using Pneumatic, Electric or Hydraulic actuation methods.

Available in either ANSI or API design, manufacture, and end-connections, chokes area available in a range of sizes and bean ratings, and in a wide variety of materials and trim configurations.

The GFLO Choke multi-orifice trim consists of carefully engineered diametrically opposed holes designed to divide the process into a number of flow streams. These flow streams are directed into the centre of the trim, where opposing streams collide, dissipating the throttling energy within the flow stream itself at the centre of the trim, away from valve components.

The inherent flow over design of the GFLO Choke angle body together with the use of hardened trim materials further ensure valve components are protected from erosion and wear.
