A210 New Generation Pneumatic Actuators |
|
|
|
|
|
InnovativeInnovative new design PROVAL ProAir (PA) Type pneumatic actuators are rack & pinion design, available in both double acting and spring return types. New design actuators are equipped as standard with both opening and closing travel adjustment bolts. In addition the state of the art technology of PA Type actuators reduced the size while generating higher torque output values. |

Technical Specifcations |
|
|
|
|
|
1. Indicator |
|
|
|
Position indicator with NAMUR is convenient for mounting accessories such as limit switch box, positioner and so on. |
|
|
|
|
|
|
2. Pinion |
|
|
|
The pinion is high-precision and integrative, made from nickelled-alloy steel, full conform to the latest standards of ISO5211, DIN3337, NAMUR. The dimensions can be customized and the stainless steel is available. |
|
|
|
|
|
|
3. Actuator Body
According to the different requirements, the extruded aluminum alloy ASTM6005. Body is treated as hard anodized, alternative can be PTFE or Nickel plated for very agressive environments. |
|
|
|
|
|
|
|
|
|
4. End Caps
Die casting aluminum powder polyester coated or PTFE/Nickel plated for very aggresive environments |
|
|
|
|
|
|
5. Pistons
The twin rack pistons are made from die-casting aluminum. Symmetric mounting position long cycle life and fast operation reversing rotation by simply ivnerting pistons
|
|
|
|
|
|
|
|
|
6. Travel Adjustment
The two independent external travel stop adjustment bolts can adjust ± 5° at both opening and closing directions easily and precisely. 0-90° full scale limit position adjustment is also available optionally.
|
|
|
|
|
|
7. High Performance Springs
Pre-loaded coating springs are made from the high quality material for resistant to corrosion and longer cycle life, which can be dismounted safely and conventionally to satisfy different requirements of torque by changing quantity of springs. |
|
|
|
|
|
|
|
8. Bearings & Guides
Made from low friction,long-life compound material,to avoid the direct contact between metals. The maintenance and replacement are easy and convenient. |
|
|
|
|
|
|
|
|
9. O-Rings
NBR rubber O-rings provide trouble-free operation at standard temperature ranges. For high and low temperature applications Viton and Silicone seals are available optionally. |
