PAX Range Linear Actuators

Part Number: PAX

PAX Range Linear Actuators

PAX units are flexible, low voltage actuators that are designed for use in remote, explosionproof locations. They are ideal for midstream and downstream systems that demand precision and reliability, such as within natural gas. Many PAX actuators have been supplied to gas utility companies at natural gas pressure reducing stations to provide automation. This eliminates expensive manual field operation. PAX technology provides simple and rapid compliance to emissions guidelines. They are also suitable for use within water distribution automation networks.

The wider PAX range is made up of linear actuators and motorised regulators. Common applications include pump stroke control, valve control, test equipment and the automation of mechanical spring-loaded pressure regulators. PAX1 linear actuators are low-powered; their use dramatically reduces power usage while maintaining position. This low power benefit makes them an environmentally sensible choice, while simultaneously increasing the efficiency of pilot operated valve automation within natural gas and water distribution systems.

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