The IMI Air-Lock (AL) Device isolates pneumatic actuators from control devices when air pressure falls below a set point. It features an adjustable pressure switch and dual 3-way valves in a single unit. The device activates instantly upon pressure loss and resets automatically when pressure rises by 1 bar. Available in anodised aluminium or stainless steel 316, it offers reliable performance in various conditions, including offshore and sandstorm environments. Its compact design reduces installation time, space, and cost, ensuring seamless integration into actuator systems where maintaining control during pressure fluctuations is critical.
