Description

HQT Explosion-Proof Quarter-Turn Electric Actuators can be used for driving and controlling the butterfly valves, ball valves, plug valves (part-turn valves with 90ºmovement), the actuators can be either remotely controlled or locally controlled, Its widely used in the fields such as oil, chemical, power generation, water treatment ect…..The protection class is IP67, And the Explosion proof class is ExdIICT4 ,Its Automation Maximum Output Torque is 3000N.m. The products conformto JB/T8528-97 (Technical conditions for non explosion proof electric actuators)

  • Height above sea level: ≤1000m
  • Humidity:≤90% (25℃)
  • No strong corrosion media at working enviroment.
