Overview

THORNHILL CRAVER UNIBOLT choke valves are available for pressures up to 20,000 psi with either alloy steel or 12% chrome stainless steel body. They are provided with a ring-groove or taper-type seal, depending on size and pressure. Bean sizes can be specified from 1/64 to 2 in [0.040 to 50.8 mm]. Engineered for heavy-duty, maintenance-free performance, the THORNHILL CRAVER UNIBOLT choke valve is commonly selected for a number of applications, including

  • wellheads
  • well testing
  • manifolds
  • process facilities.

The unique coupling between the blanking plug and the body ensures reliability and safety compared with other methods. The connection is made by means of the interlocking shelf design rather than by conventional threads or flanges.
