Rotork releases AC version of linear actuator

The addition of an AC power variant allows for longer cable runs without degradation of the power supply.

Rotork has recently launched an AC power variant of its PAX1 low voltage actuators designed for use in remote explosion-proof locations.

The actuators offer a thrust output of up to 2,890 N (650 lbf), enabling control of most regulators, small valves and pumps. They are also capable of controlling pressure ranges of 0-0.5 psig to 0-3,000 psig and applications include pump stroke control, valve control, test equipment and the automation of mechanical spring-loaded pressure regulators.

They are hazardous area rated to FM, CSA and ATEX and have high levels of ingress protection; NEMA 4X, Type 6P, IP66 and IP68 (7 m for 72 hours), increasing the areas in which they can be used. They also have a wide ambient temperature range of -40 to +80 °C (-40 to+176 °F).

The addition of an AC power variant allows for longer cable runs without degradation of the power supply, so the PAX series units can be installed within existing installations where DC power does not exist or is too difficult to run. The PAX series significantly reduces power usage while maintaining position.
