Installation notes
Commissioning and Inspecting the Adjustable Cushioning at Both Ends
The cushioning at both ends of the AC Series is adjustable. During installation and commissioning, check the cushioning effect and end-of-stroke positioning at both ends. During maintenance and inspection, check for end impacts, abnormal vibration, or positioning issues, and verify the cushioning settings as required.
FAQ
Which valves and applications is the Neles Easyflow AC Series suitable for?
The AC Series consists of pneumatic piston-cylinder linear actuators designed for rapid operation of gate valves, globe valves, dampers, and other linear-motion valves. It is suitable for plant automation, general process applications, and modulating and on-off applications with high cycling frequencies.
Which main technical parameters should be checked when selecting an AC Series actuator?
Selection should be based on the valve thrust requirement, operating pressure, ambient temperature, and protection requirements. The AC Series has a thrust range of 453 to 96220 N, a maximum operating pressure of 10 bar, a temperature range of -20 to +80 °C, and an IP67 protection rating. The stated thrust range covers the series; the selected size must match the required thrust.
Which design features of the AC Series reduce friction and support long service life?
The AC Series uses extruded aluminum profiles or steel cylinders with micro-honed surfaces to reduce friction. Quad seals combined with a lifetime lubrication design support low friction and long service life. The robust construction uses steel and cast iron for heavy-duty mounting components.
Is the cushioning at both ends of the AC Series stroke adjustable?
The AC Series is equipped with adjustable cushioning at both ends. The cushioning at each stroke end can be adjusted separately. This feature is one of the actuator's structural characteristics.
When the AC Series is used for emergency shutdown, how should the actuation type and safety capability be distinguished?
The AC Series covers emergency shutdown applications and has SIL 3 capability. Its listed actuation type is double-acting; spring-return versions require consultation with Neles. Double-acting configuration, spring-return configuration, and SIL 3 capability are separate selection criteria, so a double-acting model should not be considered a spring-return model by default.
