DR-Type Gate & Seat Drilling Chokes

Available in 2” and 3” nominal sizes (DR20 and DR30 models).

Working pressures: 10,000 psi to 15,000 psi models as standard. High pressure models also available, up to 25,000 psi.


Features and Benefits

  • Design includes reversible gate & seat components, allowing up to twice the service life of a normal non-reversible drilling choke trim.
  • Gate & seat trim design is highly blockage resistant, with potential to perform a flushing stroke in the event of large solid material to flush through any debris and restore normal operation.
  • Controlling components (gate & seat) are made from solid tungsten carbide for maximum durability.
  • Available in manual and hydraulically actuated configurations.
  • Actuated configuration includes a pneumatic pressure-type position indicator as standard. A digital position sensor option is also available.
  • DR20 provides a 1.75” orifice diameter.
  • DR30 provides a 3.00” orifice diameter.
