V46N Series Reverse Acting Valve

Description

The V46N Series are reverse acting pressure
actuated modulating valves used on either
open or closed loop coolant systems.
Reverse acting valves open on a refrigerant
pressure decrease. They are generally used
in parallel with a direct acting valve for heat
pump applications or for bypass operation.

Refer to the V46 Pressure-Actuated

Water-Regulating Product Bulletin

(LIT-125687) for important product

application information.
