Description
Johnson Controls V46AA-56 Pressure Actuated Water Regulating Valve
The Johnson Controls V46AA-56 is a commercial-grade, pressure actuated water regulating valve engineered to automatically modulate condenser water flow in response to system refrigerant pressure. Designed for reliable performance in demanding commercial HVAC and refrigeration applications, this valve helps maintain optimal system efficiency by opening as head pressure rises — protecting compressors and maximizing energy savings.
Key Features
- Pressure actuated operation — opens on rise of refrigerant pressure for automatic flow control
- 3/8″ NPT connection for straightforward installation into standard commercial piping systems
- Wide operating pressure range of 100–300 PSI to accommodate a broad range of commercial refrigeration and HVAC systems
- 36″ capillary tube provides flexible sensing element placement during installation
- Open-on-rise action helps protect compressors from high head pressure conditions
- Built for commercial use — durable construction suited to continuous-duty environments

Application
The V46AA-56 is ideal for use on commercial water-cooled condensing units, chillers, and refrigeration systems where condenser water flow must be regulated in response to refrigerant head pressure. Its open-on-rise configuration ensures condenser water is admitted when system pressure climbs, preventing nuisance high-pressure trips and extending equipment life.
