Tritex II™ Electric Actuator

Tritex IITM electric actuators are precise, fast and reliable DC-powered actuators used for on/off or modulating control with Norriseal valves.

Tritex II actuators are a zero-emissions replacement for gas-powered pneumatic devices, improving environmental compliance and eliminating the loss of valuable product.

Tritex II actuators deliver increased speed, precision and reliability in on/off or modulating control. With one of the largest installed bases in the U.S., Norriseal valves with Tritex II actuators deliver improved performance to reduce your costs and enhance process efficiency.

Tritex II actuators outperform other electric and pneumatic actuators by providing small hysteresis and dead band, quick response to small signal changes, and stable dynamic responses. Digital Input/Output and analog control options offer flexibility and allow direct communication with SCADA systems.

Typical Applications

  • Flow control
  • Choke
  • Dump
  • Pressure control upstream/downstream/differential
  • Compressor control
  • Gas lift
