Adjustable Choke Valves

The THORNHILL CRAVER® UNIBOLT Choke design is field proven in a wide range of applications. Available with alloy steel or 12% chrome stainless steel body, it is provided with a ring-groove or taper-type seal depending on size and pressure.

Adjustable choke styles are Standard, Long Nose Heater, Force Balanced and Steam. Engineered for heavy duty, maintenance- free performance, The Thornhill Craver UNIBOLT Choke is commonly selected for a number of applications, including:

Production manifolds
Wellheads
Heaters
Critical Services
Well testing
Well clean-up

The UNIBOLT coupling between the body and yoke is a unique design feature that ensures superior reliability and safety over other methods. The connection is made by means of the UNIBOLT inter-locking shelf design rather than by conventional threads or flanges.
