Scotch yoke pneumatic actuator

  • Extremely wide torque range for large valves
  • Adjustable travel stops for precise positioning
  • Heavy-duty housing for impact and fatigue resistance
  • Supports air-to-open, air-to-close and fail-safe operation
  • Scotch yoke design provides higher breakaway and seating torque
    • FVHOPES scotch yoke pneumatic actuators adopt a yoke mechanism that delivers maximum torque at the beginning and end of valve stroke. They are ideal for large-size valves, high-pressure and high-torque applications in oil & gas, petrochemical and heavy industries.
