• Designed and Manufactured as per ANSI b 16.34, BS 5251

FEATURES

1. Actuator Body:Extruded Aluminium Alloy body is hard anodised to protect the internal and external components against corrosion, SpecialHoned Internal Surface reduces the friction on moving pistons and extends the life cycle of the actuators. Alternative coatingsare available such as ENP (Electroless Nickle Plating), Fiber Powder Coated, PFA, ECTFE for-more aggressive environments.2. End Caps:Diecasted aluminum end caps are primerely Alodine Chromatized coated which provides longer life cycles against corrosionand reduces wearing resistance.Secondary standard coating is powder polyester coating and also ENP, PFA, ECTFE etc coatingsare offered alternatively for agressive environments.3. Pistons:Diecasted aluminum twin rack pistons are equipped with slide guides and seals in high engineered plastic. AlodineChromatized coated pistons ensure longer life cycles against corrosion and wearing resistance.Pistons that are identical on bothsides allow reverse rotation simply by inverting the pistons.
4. Travel Adjustment:Bi-directional external travel stop adjustment bolts can adjust the position ± 5" between 850 to 950 at both opening and closingdirections for accurate valve allignment. 0-90° full scale limit position adjustment can also be offered optionally.5. Pinion (Drive Shaft):Anti Blow Out proof alloy steel pinion is electroless nickel plated in order to reduce the friction, provide maximum wearresistance and protection against corrosion under severe conditions as it fully conforms to the latest standards of IS0521 1 ,D1N3337,NAMUR. Double square, paralel or diagonal square or key way type shaft can be supplied in accordance with customerdemands.6. Preloaded Springs:Modular Pre Loaded Spring Cartridge design in high grade coated steel springs provide great safety and corrosion resistance infail safe and emergency shut down operations. Also these springs can be used for both high & Low Temperature applications.7. Position Indicator:All actuators are equipped with regular position indicator showing the current state of the actuators and valves. Top of Actuatorhas a NAMUR slot to engage with all popular sensors and positioners.
8. Bearings:Low friction Bearing & guides provide high life cycle to ensure trouble free operations and stability during operation ofactuators.9. Seals:NBR rubber 0-rings provide trouble free operation at standard temperature ranges between -20 °C to +80 °C temperatureranges. For high and low temperature applications Won (-20 °C + ISO °C) and Silicone (-50 °C + 180 °C) seals are availableoptionally10. Fasteners:Stainless steel fasteners for long life corrosion resistant application.11. Traceability:Each individual actuator is assigned an unique identification number allowing full traceability.
