Control Master Chokes

  • Shop Primary Image
    The model CM is an extreme duty hydraulic choke designed with field maintenance in mind.

    Features:

    • Piston actuator – provides fast movement for pressure manipulation.
    • Quick removal actuator.
    • 2” trim size, tungsten carbide
    • Piston actuator can be modified to a worm gear.
    • Reversible gate and seat.
    • Solid 2” tungsten carbide gate and seat–patented design provides maximum erosion resistance.
    • Pressure balanced gate – reduces operating force.
    • Downstream wear sleeve – extended-length solid tungsten carbide seat provides wear protection on the body.
    • Large buffer cavity – slows velocity and distributes the impact of solids.
    • Bleeder port to relieve pressure from choke body prior to bonnet removal for inspection or maintenance.
    • Full-rated working pressure throttling capability.
    • Exceeds ANSI Class V drop tight seat seal shut off.
