P-Series Piston Actuators

Designed for fitting onto a wide range of Control valves, louvres or dampers, these high power actuating units are for use in on/off, or modulating service with increased thrust capacity compared to diaphragm actuators.

Available as either a single acting or double acting unit. The design is field reversible and utilises a wide range of springs to provide positive fail action. Positioners are normally yoke mounted and of the double-acting type providing air to both sides of the piston and giving a robust and precise unit that is resistant to load fluctuations.

Design Features:

  • High thrust capability, capable of using air supplies up to 150psig (10bar)
  • Multi-size options with long stroke capability
  • Robust components for trouble-free, low-cost ownership
  • Positive spring air fail action, which is not field reversible
  • Lightweight corrosion resistant construction
  • Rotary options available

Benefits

  • High degree of stem positioning accuracy
  • Cylinder design has lower air consumption than a comparable diaphragm actuator
  • Highly stable providing inherent stiffness over full stroke
  • Highly responsive with minimum latency on movement or positioning
  • High resolution of stem positioning for up to 12in strokes as standard with longer strokes available
  • Adjustable actuating forces to suit different applications
  • Rigorous in-field testing
  • Manufactured to ISO 9001 certification
