ChokemasterTM Drilling Choke

Available in manual, hydraulic and electric servo motor actuation, AXON’s ChokemasterTM Drilling Choke features a modular design that can be customized to specific rig requirements, as well as adapted when these requirements evolve. This ability to configure a basic valve platform with à la carte operation selections, in addition to maintaining complete spares interoperability within the equipment fleet, allows for ultimate flexibility. Featuring industry-leading, low-range controllability, the gate and seat assemblies are also reversible for two complete seal and wear areas. Furthermore, our drilling choke’s improved bonnet design allows for increased wear life.
