P-Series Piston Actuator

Product Description

P-SERIES ACTUATOR

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 utilizes 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 field reversible
• Lightweight corrosion resistant construction
• Rotary options available

Performance 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
