Actuators and Controls “Acutorque” Stainless Steel Actuator Design and Construction 5 7 9 3a 6 2 4 10 1 3b 1. Investment Cast Body 6. Stainless Steel Pistons Assures manufacturing of other special alloys, such as Monel Precision cast pistons are guided through full face engagement with the pinion and piston guide 2. Unique Drive Pinion One piece stainless steel alloy shaft, precision machined gear and teeth for precise control 3. Bearings Replaceable top and bottom TFE Pinion Bearings to ensure low friction, stability above 400°F, and chemical resistance 4. Travel Stops Provides +/-4° travel adjustment in outboard direction 5. Accessory Mounting Manufactured to NAMUR to provide international standardized mounting 7. NAMUR Slotted Shaft Standard to provide a self-centering positive drive for positioners, a variety of switches 8. Actuator Mounting Manufactured in accordance with ISO 5211 to ensure mounting the actuator directly on valves 9. Pre-loaded Cartridges Converts a standard double acting actuator to a spring return unit by simply removing the end caps and adding the spring cartridges 10. NAMUR Solenoid Mounting International standard for direct mounting of solenoid valves 11

Actuators and Controls Operation The Apollo® Acutorque actuator is manufactured with an integral and internal air manifold. The solenoid mounting pad is manufactured to Namur dimensional standards as to allow for the direct mounting of various manufacturers’ solenoid valves and other flow control devices. For applications not requiring a direct mount solenoid valve, ports are tapped to NPT standards (American National Standard taper threads). Reverse Rotation When required, a clockwise rotation of the drive pinion, by means of air to PORT A can be achieved by reversing the pistons inside the...

Actuators and Controls Features Corrosion Resistance fications is greatly enhanced. All metal components are cast or machined from Stainless Steel or Monel, which offers excellent resistance to most corrosive chemicals as well as industrial atmospheres. No Lubrication All actuators are factory lubricated for the optimum life of the actuator under normal conditions. Teflon® piston bearings are used because of their self-lubricating properties. Simple Maintenance Each actuator is designed for ease of maintenance. Should you wish simply to change a spring rating or completely rebuild a unit, total...
