Cowan Dynamics has announced the release of the next generation AS Series, Spring-Return Pneumatic Valve Actuator. Based on the AS Series, the Compact version was designed specifically for applications where space is a premium. The AS Compact provides up to 57% shorter and 42% lighter canisters compared to the standard model.
