Honeywell VP522

Honeywell's VP522 series includes pneumatic valves and rebuild kits. The VP522 valves are pneumatic 3-pipe valves designed for water systems. VP522A valves control the flow of hot or cold water from the water supply pipes to fan coils. VP522B diverting valves are return-water valves that operate in conjunction with VP522A valves in 4-pipe systems to isolate the hot and cold water circuits. VP522A and VP522B valves are available with different valve sizes and capacity index ratings. VP522 rebuild kits contain buttons with screws, stems, disc holders, and packing. These kits are used to rebuild VP522 valves.
