Belimo B309B+TR24-3 Valve Assembly 340155-7024 The unit supports both direct-acting

The unit supports both direct-acting (DA) for cooling with reheat and reverse-acting (RA) configurations

it must be mounted with the actuator above the horizontal plane to prevent moisture from damaging the motor

you must install a 500 Ohm resistor (typically ZG-R01) across the input

This HVAC ignition controller is built to withstand the rigors of heavy-duty cycles

and birds from entering the direct vent gas furnace intake and exhaust flues

Belimo B309B+TR24-3 Valve Assembly 340155-7024 The unit supports both direct-actingThe Belimo B309B+TR24 3 Valve Assembly is a high precision solution for managing hydronic systems in commercial HVACR applications. This 3 way characterized control valve (CCV) features a 1 2 inch NPT connection and is designed for mixing or diverting chilled or hot water with up to 60% glycol. With a Cv of 0. 8, it provides an equal percentage flow characteristic through the A port, effectively preventing control loop hunting and maintaining stable
