1. Actuator BodyExtruded Alu Alloy ASTM6005 body is hard anodised to protect the internal and external components against corrosion, which reduces the friction on moving pistons and extends the life cycle of the actuators. Alternative coatings are available such as ENP (Electroless Nickle Plating), Powder Polyester, PFA, ECTFE for more aggressive environments.
2. End CapsDiecasted aluminum end caps are primerelyAlodine Chromatized coated which provides longer life cycles against corrosion and reduces wearing resistance. Secondary standard coating is powder polyester coating and also ENP, PFA, ECTFE etc coatings are offered alternatively for agressive environments.
3. PistonsDiecasted aluminum twin rack pistons are equip-ped with slide guides and seals in good quaility. Alodine Chromatized coated pistons ensure longer life cycles against corrosion and wearing resistance. Pistons that are identical on both sides allowreverse rotation simply by inverting the pistons.
4. Pinion (Drive Shaft)Alloy steel pinion is electroless nickel plated in order to reduce the friction, provide maximum wear resistance and protection against corrosion under severe conditions as it fully conforms to the latest standards of ISO5211, DIN3337, NAMUR. Double square, paralel or diagonal square or key way type shaft can be supplied in accordance with customer demands.
5. Travel AdjustmentBi-directional external travel stop adjustment bolts can adjust the position ±5° between 85° to 95° at both opening and closing directions for accurate valve allignment. 0-90° full scale limit position adjustment can also be offered optionally.
6. Preloaded SpringsCardridge design in high grade coated steel springs provide great safety and corrosion resistance in fail safe and emergency shut down operations.
7. IndicatorAll actuators are equipped with regular position indicator showing the current state of the actua-tors and valves.
8. Bearings & GuidesLow friction piston guides provide high trust and stability during operation of actuators.
9. SealsNBR rubber O-rings provide troublefree opera-tion at standard temperature ranges between -20 °C to +80 °C temperature ranges. For high and low temperature applications Viton (-20 °C ~ +150 °C) and Silicone (-35 °C ~ +80 °C) seals are available optionally.
10. FastenersStainless steel fasteners for long life corrosion resistant application.
11. TraceabilityEach individual actuator is assigned an unique identification number allowing full traceability.

Function - double actingPneumatic ActuatorsPart List
Working Principles 90° Double Acting Pneumatic Actuators Double acting actuators are rotated by supplying air to related port until it reaches desired position
Counterclockwise Rotation (CCWR)Air to port B forces the pistons inwards, causing the pinion to rotate clockwise while the air is exhausted from port A.
Air to port A forces the pistonsoutwards, causing the pinion torotate counterclockwise while theair is exhausted from port B.
Clockwise Rotation (CWR)Air to port B forces the pistonsinwards, causing the pinion torotate counterclockwise whilethe air is exhausted from port A.
Air to port A forces the pistonsoutwards, causing the pinion torotate clockwise while the air isexhausted from port B.
90° Spring Return Pneumatic Actuators Single acting actuators are rotating one side by air while the springs are loaded and return action is done by means of spring force
Counterclockwise Rotation (CCWR)Loss of air at port B, causingthe energy stored springs toforce the pistons inwards androtating the pinion clockwise.
Air to port A forces the pistonsoutwards, causing the pinion torotate counterclockwise whilethe springs are compressed
Clockwise Rotation (CWR)Loss of air at port B, causing theenergy stored springs to forcethe pistons inwards and rotatingthe pinion counterclockwise.
Air to port A forces the pistonsoutwards, causing the pinionto rotate clockwise while thesprings are compressed.
