Johnson Controls V46AE-1 Valve

The Johnson Controls V46AE-1 is a standard-flow, 1-1/4 inch NPT pressure actuated water regulating valve engineered for high-demand commercial HVAC and refrigeration systems. Built with a rugged cast iron body, this direct-acting valve is specifically designed for use with non-corrosive refrigerants. It features an adjustable opening point range of 70 to 260 PSI, allowing technicians to fine-tune head pressure for optimal condenser efficiency. The inclusion of a 30-inch capillary with a 1/4-inch flare nut (Style 45) provides a reliable connection to the high side of the system, ensuring precise modulation of water flow in response to refrigerant pressure changes. This valve is a fundamental component for maintaining stable head pressure in water-cooled systems, especially in applications where HVAC water valve replacement is required to restore system balance. Professional installers value the V46 series valve for its field-proven durability and consistent performance in demanding mechanical environments.

• Field Serviceability: Designed for straightforward installation and maintenance by service contractors.

Common Questions

What is the maximum water temperature rating for the V46AE-1?
The valve is typically rated for water temperatures up to 170°F (77°C), making it suitable for most standard cooling tower and city water applications.

Can this valve be used with ammonia systems?
No, the V46AE-1 is designed specifically for non-corrosive refrigerants. For ammonia applications, a stainless steel or specific ammonia-rated valve must be used.

How do I adjust the opening point?
The opening point is adjusted by turning the tension screw on the spring housing. Tightening the screw increases the pressure required to open the valve, while loosening it lowers the opening point.
