Description
The VU442/VU842, VU443/VU843, and VU444/VU844 Fan Coil Valve Actuators are used in conjunction with the VU52, VU53 and VU54 valves for 2-position control of low pressure steam, or hot and chilled water with up to 50% glycol in commercial HVAC equipment such as fan coil units, terminal reheat coils and convectors. These valves are humidity resistant and are suitable for use in condensing, noncorrosive environments.
