The ValtekSul spring cylinder actuator is a powerful, high-performance pneumatic unit that provides positive throttling operation for automatic globe control valves.

The LA Series actuator is fully field reversible for air-to-open or air-to-close action without additional parts; a spring provides fail-safe operation.
