The Series 3HBAV is an electrical ball valve ideal for flow control in hot and
cold water HVAC systems. These valves are typically used in conjunction with
air conditioning systems, heating systems, water treatment and production
industries. The 3HBAV is electrically driven open and/or closed via a
bidirectional AC motor. The electrical valve offers a detachable actuator with
position switches and indicator. The 3HBAV is available with modulating or
floating actuators.
