Pneumatic actuator, IA Motion IA700S, InterApp

Possible Applications

This pneumatic spring-return actuator is deployed primarily in critical process-control loops within water treatment facilities, chemical processing plants, and power generation stations where fail-safe valve positioning is mandatory during a sudden loss of plant air or electrical supply. It is typically mounted to large quarter-turn butterfly or ball valves installed in heavy-duty pipeline networks managing corrosive fluids, cooling water loops, or slurries. The high-torque output generated by the internal rack-and-pinion mechanism makes it exceptionally well-suited for automating heavy industrial valves that require substantial breakaway force to overcome viscous media or high differential pressures. Furthermore, its reliable mechanical spring return ensures immediate closure or opening of safety-critical lines to prevent catastrophic spills, protect downstream equipment, and maintain facility integrity during emergency shutdowns.
