Description
Johnson Controls V46AB-1 Pressure Actuated Water Regulating Valve
The Johnson Controls V46AB-1 is a commercial-grade, direct acting pressure actuated water regulating valve engineered for reliable refrigerant system performance. Built from durable cast brass, this valve is designed for use with non-corrosive refrigerants and provides precise water flow regulation based on refrigerant head pressure — helping maintain optimal system efficiency and protecting compressors from high-pressure conditions.
Key Features
- Connection size: 1/2″ NPT for straightforward installation into standard piping systems
- Opening point pressure range: 70 to 260 PSI, offering wide-range adjustability for diverse commercial applications
- Standard flow, commercial type construction for heavy-duty, continuous-duty use
- Cast brass body for corrosion resistance and long service life
- Direct acting design — no external power source required for operation
- Suitable for use with non-corrosive refrigerants
- Includes 30″ capillary tube with 1/4″ flare nut for easy connection to the refrigerant circuit
- Style 45 configuration
How It Works
The V46AB-1 senses refrigerant head pressure via its capillary connection and automatically modulates condenser water flow to maintain the desired condensing pressure. As head pressure rises, the valve opens to increase water flow through the condenser; as pressure drops, the valve closes to conserve water. This self-regulating action protects the refrigeration system and improves energy efficiency without the need for electronic controls.
Typical Applications
- Commercial refrigeration systems
- Water-cooled condensing units
- Chiller and cooling tower circuits
- HVAC systems using non-corrosive refrigerants
