Johnson Controls V46AE-17 Regulating Valve

Maintain precise head pressure control in your water-cooled condenser systems with the Johnson Controls V46AE-17. This direct acting water regulating valve is engineered to modulate the flow of water or glycol to ensure consistent system performance under varying heat loads. Built with a rugged cast iron body, this 1 1/4" NPT commercial-grade valve is optimized for non-corrosive refrigerants and features a high-pressure 70 to 260 PSI opening point range. The Style 5 pressure element, equipped with a 1/4" external flare fitting, provides responsive sensing to prevent compressor short cycling and optimize heat exchange. Designed for veterans who demand reliability, the V46 series internal design features no close-fitting or sliding parts in water passages, which virtually eliminates chatter and water hammer during operation. Whether you're handling a condenser pressure control retrofit or a new commercial install, this modulating water valve ensures the refrigeration cycle remains balanced and efficient in high-demand environments.

Key Benefits

• Direct Acting Reliability: Opens immediately upon refrigerant head pressure increase to maintain stable condensing temperatures.
• Broad Operating Range: The 70 to 260 PSI adjustable range supports both low-pressure and high-pressure refrigerant applications.
• Anti-Chatter Design: Internal mechanical geometry is optimized to prevent water hammer, protecting the piping infrastructure.
• Field Serviceability: Designed for easy manual flushing to clear sediment without disturbing the pressure setting.
• Standard Flow Capacity: Ideal for standard flow commercial water-cooled systems requiring NPT pipe connections.

Common Questions

How do I adjust the opening point on the V46AE-17?
Use a standard service wrench to turn the 5/16" square head adjustment screw at the top of the spring housing. Turning the screw counterclockwise increases the opening point pressure, while clockwise turns decrease it.

What is the proper mounting orientation for this valve?
For optimal performance and drainage of oil or refrigerant away from the Style 5 pressure element, install the valve vertically with the adjustment screw on top and the bellows housing at the bottom.

Can this valve be used with glycol solutions?
Yes, the V46 series is compatible with water and glycol mixtures, making it suitable for both open and closed-loop commercial cooling systems using non-corrosive refrigerants.
