Aircon Pneumatic Rack and Pinion Valve Actuators

Aircon pneumatic actuators are provided in both double acting and spring return configurations and come standard with an extruded aluminum body with hard anodized finish and polished internal surfaces.  Their die cast aluminum end caps are coated with a powder-polyester paint and can be supplied with a  PTFE or nickel-plated finish if desired. The largest size double acting Aircon pneumatic actuator can output up to 1,585,800 in-lbs of torque and feature independent travel stop adjustment, having a range from 5º to 90º rotation. The spring return version will provide up to 398,213 in-lbs of torque.  Both feature cycle lives up to 1,000,000 cycles and are used for both valve automation and other pneumatic actuation applications such as robotics for pushing, pulling, ejecting, opening and closing actions.

Features:

• Extruded aluminum body with hard anodized finish

• Die cast aluminum end caps with powder coated paint, PTFE or nickel plated finish

  • Special corrosion resistant SS bodies and end caps are optional

• Position indicator with NAMUR slot for accessory mounting

• Precision nickel alloy steel blow out proof pinion in conformance to ISO 5211 and NAMUR

• Dual opposed rack pistons with low friction bearings and guides

• Linear torque output through its 0º-90º stroke

  • Special stroke and 3-position actuators are available as an option

• Independent travel stop adjustments of ±5º in both open and closed positions for precise valve alignment

• Performance spring cartridges for increased safety and extended spring life

  • Enables converting a double acting to a spring return version by simply adding spring cartridges

  • Different torques can be obtained by changing the quantity of spring cartridges

• NAMUR solenoid mounting enable direct mounting to actuator

• External fasteners are 304SS

• All actuators are manufactured within a registered ISO-9001-2000 facility

• 100% of actuators are inspected and tested prior to packaging and shipment

• Each actuator is serialized for traceability

Proper Sizing of Pneumatic Valve Actuators

• Determine the maximum torque requirement for your valve

• We suggest adding a safety margin of 20% for double acting pneumatic actuators and 10% for spring return pneumatic valve actuators

• Refer to the applicable pneumatic actuator brochure and based upon your compressed air pressure, select the actuator which satisfies the maximum torque requirement & safety factor
