Rotork Fairchild - Model PAX1 -Actuators for Hazardous and Remote Environments
PAX1 linear actuators are specialized devices designed specifically for use in remote or explosion-proof locations, particularly within the oil and gas sectors. These actuators cater to midstream and downstream systems that require high precision and reliability, such as natural gas pressure reducing stations. Implementing PAX actuators in such settings significantly reduces the need for manual operations, thus ensuring compliance with emissions rules and enhancing automation. The PAX range includes both linear actuators and motorized regulators, applicable in control tasks such as valve operation, pump stroke control, and managing pressure regulators. These actuators boast a low power design, consuming less than 1 watt during standby, making them an energy-efficient choice. Their features include a robust IP rating for dust and water resistance and a wide operational temperature range, supporting both AC and DC power options, which make them versatile for varied environmental conditions.
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.
