Fan Coil Valve Actuators
The VU443, VU444, VU843, and VU844 Fan Coil Valve
Actuators are used in conjunction with the VU52, VU53, and
VU54 fan coil valves for controlling the flow of hot or chilled
water. These valves are humidity resistant and are suitable for
use in condensing, non-corrosive environments.
