Johnson Controls V46AB-1 Regulating Valve

The Johnson Controls V46AB-1 Regulating Valve is a direct acting pressure actuated water regulating valve specifically engineered for maintaining refrigerant head pressure control in systems using non-corrosive refrigerants. This 1/2" NPT commercial water valve features a cast brass body and a robust pressure-balanced design, ensuring stable performance despite fluctuations in water pressure. For the technician in the field, the V46AB-1 provides a reliable opening point range of 70 to 260 PSI, making it ideal for water-cooled condenser applications in ice machines, computer room air conditioning units, and refrigeration cases. It comes equipped with a 30-inch capillary and a 1/4" flare nut (Style 45) pressure element for straightforward integration. This unit serves as the direct replacement for V46AB-22 and V46AB-17; simply cut the flare to adapt to a style 34 connection when replacing older V46AB-17 models. The take-apart construction allows for full interior access without pumping down the system.

• Direct Acting Operation: Valve opens on pressure rise to effectively modulate flow through the condenser.
• Broad Compatibility: Designed for use with standard, non-corrosive refrigerants and systems utilizing water or glycol.
• Enhanced Serviceability: Features an accessible range spring for manual flushing and a take-apart design for easy maintenance.
• Durable Construction: Cast brass body and corrosion-resistant internal components extend service life in demanding commercial environments.
• Standardized Connections: 1/2" NPT water connections and Style 45 pressure connections simplify the installation process.

• How do I adjust the opening point on the V46AB-1? Use the range adjustment screw to set the opening point within the 70 to 260 PSI range while the system is operating under load.
• What is the maximum water temperature for this valve? This valve is rated for a maximum water temperature of 170°F (77°C) and a maximum water pressure of 150 PSI.
• Can I use the V46AB-1 with ammonia systems? No, this commercial brass model is for non-corrosive refrigerants only; ammonia applications require specific maritime or ammonia-rated steel valves.
