Proximity® Series QV indicates valve position locally and remotely.

Proximity® Series QV position indicator is utilized in valve automation package. Quarter turn valves such as ball and butterfly valves are often automated with pneumatic or electric actuators. The actuator connects to the shaft of the valve and rotates it. Usually the actuator has a shaft of its own that comes out of the top and rotates as the actuator rotates the valve. The QV mounts onto the top of the actuator and connects to this actuator shaft for indicating valve position. When the valve is open or closed, the corresponding word "OPEN" or "CLOSED" appears in four windows 90° apart. The visual indicator also includes degree position indication of 0 to 90°. The QV is compact yet the visual indicator is large and easy to view from a distance. Adjustable position indication switches are available to remotely indicate if the valve is fully opened or closed. The QV assures proper operation of the valve and indicates problems so they can quickly be addressed.
