Valworx 576190 stainless steel rack and pinion air actuators are typically used to operate quarter turn ball valves and other quarter turn applications requiring high corrosion resistance and/or sanitation. Rugged IP66 construction is suitable for washdown applications. Quick and easy to install with standard ISO5211 valve mounting pad and double square female output drive. Spring return actuators use air pilot pressure to open and mechanical springs to close when the air is exhausted. The pilot air is typically controlled by a 3-way type manual or solenoid valve.

An optional pilot solenoid valve can be mounted directly to the side of the actuator using the standard Namur interface saving time, space and plumbing. The solenoid valve when supplied with the required pilot air pressure will allow electrical operation of the actuator.
