DD = Double acting DS = Single acting (Spring Return) Operating principle Double acting actuator - If port is pressurised and port is vented, both the pistons move outwards to the endpositions. - The moving pistons cause the pinion to rotate counter clock wise. Single acting (spring return) actuator - If port is pressurised and port is vented, both the pistons move outwards compressing the springs. - The moving pistons cause the pinion to rotate counter clock wise. - If port is pressurised and port is vented, both the pistons move inwards to their block positions. - The moving pistons cause the pinion to rotate clock wise. - If port is vented, the spring force applied to the pistons move them inwards to their block positions. - The moving pistons cause the pinion to rotate clock wise. Note: The above described operating principle is applicable for standard actuators (assembly mode ). For reverse acting actuators (assembly mode D), pressurizing the ports will result in a oposite rotation. Note: The above described operating principle is applicable for standard Fail to Close actuators (assembly mode ). For reverse acting Fail to Open actuators (assembly mode D), pressurizing the ports will result in a oposite rotation.

DPI 4.03 Rev. 0 Drive inserts Description Most of the ettis actuators are fitted with drive inserts. This enables actuators to be directly mounted onto suitable valves and eliminates the need for a bracket and coupling type mounting kit. The use of direct mounts significantly cuts the cost of the valve/actuator assembly. Standard actuators are fitted with square drive inserts in accordance with ISO 52 (or DIN 3337), but a wide variety of other inserts are also available. Special inserts may have oversize or undersize squares, double-d and shaft key way forms. Drive inserts can be supplied on factory built actuators or as loose items and are easily replaceable at distributor or end user level. Where direct mounts are not possible, for instance on valves with exposed grand packing, the use of inserts often simplifies the design of the mounting kit.

DPI 6.0 Rev. 0 ettis corrosion protection system Description: The corrosion protection system of the standard ettis pneumatic actuators consist of the following treatments or materials: De-greasing. ll aluminum parts are de-greased before the powder coating is applied by washing with an alkaline solution to assure the best bonding between the aluminum surface and the coating. 2 Powder coating. - Polyester non-tgic based powder coating for exterior use. - The powder coating is applied cold using automatic electrostatic spray equipment and is cured at minimum 90 C (374 F) offering excellent light and weather resistance. - The powder coating thickness is.5 mils (37 microns) minimum, and 2 mils (50 microns) average. - Good chemical resistance against most bases, acids, solvents, alkalis and oils at normal temperatures. - Excellent exterior mechanical durability. - The coating has passed a salt spray test according to STM 7 for 500 hours. The powder coating is virtually solvent free, and therefore environmentally friendly. 3 High grade & anodized aluminum pinion. ctuators with high grade & anodized aluminum pinions, passed a 500 hours salt spray test. Optional stainless steel pinions are available with a higher corrosion resistance. 4 Stainless steel or Deltatone treated external steel parts. External parts are stainless steel or steel alloy with a Deltatone treatment. Pinion: High grade aluminum alloy, hard anodized Technical data: Housing & Endcaps Polyester non-tgic based powder coating for exterior use.
