The V-3801-8001 Valve Actuator is used on 1/2 and 3/4 in. VG7000 Series Valves.
The V-3801-8001 is not recommended for sequencing because its relatively small size and small output force may result in unacceptable spring shift. Where pneumatic sequencing is required, the V-3000-800x Series actuators are recommended.
The V-3802-1 and V-3801-8001 are not interchangeable.
