The BMV-12A Electric On/Off Actuators provide two-position (open/closed) control and can easily be field mounted with a threaded coupling onto BMV-12B
Forged Brass Valves. A lever at the side of the actuator housing can be used to open the mounted valve manually for servicing.
BMV-12B Forged Brass Valves are primarily designed to regulate the flow of water in response to the demand of a controller in zone and fan coil applications.
They are available in Normally Closed (N.C.), or three-way mixing configurations.
The thermostats send a signal of open to the actuators which will connect the power immediately. The valves will be turned off. Then the cool or hot water will run into the fan coil unit through the valve. When room temperature reaches the set-point, thermostats transfer a signal to actuator to cut off the power and the valves will be closed(spring return).
