Share This Product:

Product Overview

Following the aim to continuously satisfy customers needs in terms of valves automation and basing on robust innovative attitude and technical knowledge, Air Torque S.p.A. offers an extended range of special actuators. The special actuators function and features are designed to meet and satisfy all innovative and safety systems in the valve automation in process control. Air Torque is the sole worldwide player offering the largest special actuators function portfolio. 

Mainly based on the 4th generation Upgrade series, but available also on PT series, the Special actuator range counts on: 

  • 100% and 50% extra travel stop limitation – for not fully open valve operation
  • RC100 travel closing limitation – for not fully close valve operation (spring return only)
  • Lock-out capability – for block and lock the actuator/ valve in open or close position
  • 120°, 135°, 180° ,… rotation – for multiport rotary valves
  • Fail mid 180° in spring return – for multiport rotary valves with 90° fail position
  • 3 position actuator 90°, 180° – for an intermediate stroke positioning
  • Fast acting actuators – for fast actuator action.
    Min stroking time up to 0.2 sec
  • Hydraulic damper – to limit the water hammer effect and preserve the valve integrity
