Pneumatic Actuator



Base Features:

1. Indicator

A position indicator with Namur mounint is standard on all pneumatic actuators for mounting accessories.

2. Pinon

The hardened alloy steel pinion is precision ground and Nickel palted (over 25μm) in order reduce friction, provide maximum wear resistance.  Full conformance with the newest standards of ISO5211, DIN3337.  The dimension cna be customized and as options, stainless steel and aluminium are also available.

3. Actuator Body

The aluminum extrusion is hard anodized (over 30μm) to protect against wear and corrosion while reducing piston friction to the absolute minimum.  Other options such as Nickel plating, PTFE and powder polyester painting are available.

4. End caps

Epoxy coated (over 200μm) die cast aluminum end caps provide maximum resistance against potentially corrosive elements.

5. Pistons

The precisely-balanced and hard anodized (over 30μm) die cast aluminum pistons are fitted with high quality tings and guides.  The twin rack and postion design creates a constat torque output on all actuators.

6. Travel Adjustment

The standard adjustment is ±5° in both the open and closed positions through easily accessible external adjustment bolts.

7. High Performance Springs

The high tensile steel springs are coated with zinc phosphate for corrosion resistance and longer service.  The preloaded springs can be safely & rapidlly disassembled.

8. Bearings & Guides:

The highly durable compound material provides high trust stability with minimum friction and long life.


NBR O-0rings provide trouble-free operation at standaded temperature ranges.  Viton an Silicome O-rings are available for high or low temperature appliacations.
