VA21

Valve Actuator

The VA21 is suited for applications requiring torque of up to 21 inch-pounds - for ball valves, metering valves and linear valves.

The VA21 is being used successfully with 1" ball valves in cryogenic machines for fast volume flow, with pressure regulators for controlling municipal water distribution, and angular position feedback applications for plant automation. Microprocessor control allows the actuator to seat the stem without damaging the valve.
