Air Purge Module for Spring Return Actuators

Flow Line Controls NX1 Air Purge Module prevents corrosive, dusty and moisture bearing air from being sucked into the spring return side of an actuator. It does this by diverting the actuator's non-spring side air into the spring chamber instead of exhausting it into the atmosphere when the actuator is cycled. Every time the actuator cycles, the spring chamber is purged with fresh instrument supply air rather than contaminated atmospheric air. This can substantially increase the service life of the Rack & Pinion actuator by protecting the spring chamber seals and springs from harmful contaminates.
