Double Acting Actuator Actuators and Controls With reference to the above diagram it can be noted that the torque of a double acting actuator remains constant throughout the complete cycle. The user can decide which model to choose according to their own specific requirements, using the following guidelines: 1. Define the maximum torque of the valve to automate. 2. To obtain a safety factor,increase the torque value chosen by 25%-50% (subject to the type of valve and working conditions). 3. Once the torque value is obtained consult the torque chart in the corresponding air pressure column, find...

PRETENSIONED SPRING Spring Return Actuator 10 Actuators and Controls The torque given by the actuator is defined by four fundamental values. Opening Rotation SOA = Start of air stroke EOA = End of air stroke Closing Rotation SOS = Start of spring stroke EOS = End of spring stroke The user can decide which model to choose according to their own specific requirements using the following guidelines: 1. Define the maximum torque of the valve to automate. 2. To obtain a safety factor increase the torque value chosen by 25% - 50% (subject to the type of valve and working conditions). 3. Once the torque...

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 actuator body (rotate 180...

15 Actuators and Controls Features Corrosion Resistance 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 disassembly and reassembly...
