Air Torque rack and pinion pneumatic actuators combine compact, modular design with fourth-generation engineering to deliver reliable and efficient valve automation. Their dual-piston construction provides consistent performance in both double-acting and spring-return configurations, while hard-anodised aluminium or stainless steel housings ensure durability in harsh environments. With ATEX, SIL3 and IP67/IP68 certification, flexible mounting options and advanced safety features, they offer dependable, low-maintenance actuation for demanding process and pipeline applications.
