Valtek Linear actuator

The VL spring cylinder linear actuator is a powerful, high-performance pneumatic actuator that provides positive throttling or on-off operation for automatic control valves. Most cylinder sizes are designed for supply pressures up to 150 psi (10.3 Bar). Using a spring to provide failsafe operation, this actuator is completely field reversible for air-to-open or air-to-close operation without additional parts. The positioner supplies air to both sides of the piston, providing stiff, precise movement and high-frequency response.
