Unitary Valve, VU52 VU53, 126, Valve Type | Honeywell MS4103

Unitary Valve

VU52; VU53

Two-way Fan Coil Valves, the VU53 high pressure zone valves are used to control the flow of hot or chilled water in commercial HVAC equipment such as fan coil units, terminal reheat coils and convectors.

IMPORTANT: These valves are not for use in systems containing dissolved oxygen.
