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.
