VA-9000 Series<br />

Electric Rotary Actuators for<br />

Two-Position and Modulating Service<br />

The VA-9000 Series Electric Rotary Actuators are<br />

designed for direct mounting in an upright position on<br />

VF Series Butterfly Valves. The VA-9000 is available<br />

in two different sizes, for two-position and modulating<br />

service on 16 through 20 in. high-pressure butterfly<br />

valves, and two-position and modulating service on<br />

20 in. low-pressure butterfly valves.<br />

All models feature two independently adjustable travel<br />

limit switches for open and closed position, each<br />

factory set for 90° valve rotation. Powered by a<br />

rugged, high-torque, single-phase reversible motor, the<br />

VA-9000 is designed to withstand stall torque for<br />

reliable performance in even the most demanding<br />

applications. Precision-cut gears and shafts are heat<br />

treated, high-alloy steel. Electroless nickel-plated<br />

output shafts provide maximum corrosion protection.<br />

The watertight actuator enclosure meets NEMA-4<br />

standards.<br />

For VA-9000 Series Actuator sizing recommendations<br />

when used on VF Series Butterfly Valves, refer to the<br />

VF Series Butterfly Valves 2 Through 20 in., Two-Way<br />

and Three-Way Product/<strong>Technical</strong> Bulletin<br />

(LIT-977205P).<br />

VA-900x-02 Series Two-Position<br />

Electric Actuators (See Figure 2.)<br />

A controller sends a 120 VAC power source to the<br />

actuator at terminals 1 and 2 (open) or 1 and 3 (close)<br />

depending on the desired movement of the valve. This<br />

signal activates the motor, causing the cam post and<br />

coupled valve shaft to rotate in the proper direction to<br />

accurately position the valve.<br />

When the valve reaches its fully open or closed<br />

position, the cams are engaged causing the<br />

corresponding limit switch to open and shut off power<br />

to the motor. Field calibration of the limit switches is<br />

not required.<br />

Note: All VA-900x-02 Series Two-Position Electric<br />

Actuators can be positioned manually using<br />

the integral handwheel. In addition, an<br />

automatic lockout safety switch prevents<br />

electrical operation during manual override.<br />

VA-900x-01 Series Modulating<br />

Electric Actuators (See Figure 3.)<br />

A controller sends a command signal (typically<br />

4 to 20 mA DC) to the actuator terminal board as<br />

illustrated in Figure 6. This signal is compared to<br />

the actual position of the valve via the feedback<br />

potentiometer. The resulting signal activates the motor<br />

to rotate the cam post and coupled valve shaft in the<br />

proper direction to accurately position the valve.<br />

When the valve reaches its fully open or closed<br />

position, the cams are engaged causing the<br />

corresponding limit switch to open and shut off power<br />

to the motor. Field calibration of the limit switches is<br />

not required.<br />

Note: All VA-900x-01 Series Modulating Electric<br />

Actuators can be positioned manually using<br />

the integral handwheel. In addition, an<br />

automatic lockout safety switch prevents<br />

electrical operation during manual override.<br />
