Johnson Controls V46AA-56 Regulating Valve

The Johnson Controls V46AA-56 is a professional-grade pressure actuated water regulating valve engineered for precision head pressure control in water-cooled condensers. Designed for commercial refrigeration and air conditioning systems, this direct-acting valve features a 3/8 inch NPT connection and an open on pressure rise configuration. With a wide adjustment range of 100 to 300 PSI, it allows technicians to fine-tune refrigerant pressures regardless of seasonal water temperature fluctuations. The inclusion of a 36-inch capillary with a 1/4 inch flare nut provides flexible mounting options for various compressor rack layouts. Built with a rugged brass body and corrosion-resistant internal components, the V46AA-56 regulating valve maintains high-efficiency heat transfer by modulating water flow based on discharge pressure. This HVAC water valve is a reliable solution for preventing high-head pressure trips and ensuring consistent system performance in demanding mechanical environments.

Key Benefits

• Precise Pressure Modulation: Maintains stable refrigerant head pressure by accurately controlling water flow rates.
• Versatile Application: Suitable for use with non-corrosive refrigerants in a variety of water-cooled condenser setups.
• Field-Adjustable Setpoints: Range of 100-300 PSI allows for site-specific calibration to maximize system COP.
• Durable Construction: Heavy-duty bellows and internal components designed for industrial-duty cycles.
• Simplified Installation: Standard 3/8" NPT threading and 36" capillary length accommodate standard piping configurations.

Common Questions

Does the V46AA-56 require an external power source?
No, this is a pressure-actuated mechanical valve that operates using the refrigerant's discharge pressure against a bellows system.

What is the action of this valve?
This model is "Open on Rise," meaning the valve opens further as the refrigerant pressure increases to provide more cooling water to the condenser.

Can this valve be used with sea water applications?
The standard V46 series is designed for fresh water; for brackish or sea water, a maritime-specific version with monel or specialized alloys is typically required.
