Technical Construction Details
Position Indicator
NAMUR-compliant indicator enables easy mounting of accessories including limit switch boxes and positioners.
Precision Pinion
High-precision integrated nickel-alloy steel pinion fully conforms to ISO5211, DIN3337, and NAMUR standards. Custom dimensions and stainless steel options available.
Actuator Body
Extruded aluminum alloy ASTM6005 construction with multiple surface treatment options: hard anodized, powder polyester painted (blue, orange, yellow), PTFE, or nickel plated.
End Caps
Die-cast aluminum with powder polyester coating available in various colors, PTFE, or nickel plating.
Pistons
Twin rack pistons manufactured from die-cast aluminum with hard anodizing or cast steel with galvanization. Symmetric mounting ensures long cycle life and fast operation.
Travel Adjustment
Two independent external travel stop adjustment bolts provide ±5° precision adjustment in both open and close directions.
High-Performance Springs
Preloaded coating springs made from corrosion-resistant materials for extended service life. Torque requirements can be met by adjusting spring quantity.
Bearings & Guides
Low-friction, long-life composite materials prevent direct metal-to-metal contact, facilitating easy maintenance and replacement.
Sealing Components
NBR rubber O-rings ensure reliable operation across standard temperature ranges. Viton or silicone options available for extreme temperature applications.
Spring Return Actuator Operation
Air pressure applied to port A forces pistons outward, compressing springs and rotating pinion counterclockwise while exhausting air from port B.
Upon pressure loss at port A, stored spring energy drives pistons inward, rotating pinion clockwise while exhausting air from port A.
