Honeywell Inc. VCZBB3500 - 2WAY VC VALVE 0.5 IN. NPT 0

Twoway Cartridge Cage Valves are intended for hydronic applications in a normal indoor environment to control the flow of hot water or chilled water glycol solution to 60 concentration. These valves are designed for zone control of heatingcooling systems or to control individual fan coil baseboard radiator or convector applications. Depending on the model selected they can be controlled by SPST or SPDT two position controller tristate (floating) or modulating proportional controller. For best control outdoor temperature compensation of supply water temperature is recommended. For troublefree operation of the product good installation practice must include initial system flushing chemical water treatment and the use of a 50 micron (or finer) system side stream filter(s). Remove all filters before flushing.
