Johnson Controls V46AT-1 2-1/2" Pressure Actuated Water Regulating Valve 70-170 PSI

The Johnson Controls V46AT-1 is a direct-acting, pressure-actuated modulating valve designed for regulating refrigerant head pressure in water-cooled condensers and commercial refrigeration systems. This 2-1/2 inch ASME flanged valve operates within a pressure range of 70 to 170 PSI, automatically adjusting water flow in response to system pressure changes to maintain optimal performance and efficiency.

Key Features:

• 2-1/2 inch ASME four-hole flanged connection for secure installation
• Direct-acting design opens on pressure increase for condenser water regulation
• 70-170 PSI opening point adjustment range
• No close-fitting or sliding parts in water passages for reliable operation in less than ideal conditions
• Corrosion-resistant materials for parts in direct contact with water to promote longer valve life
• 1/4 inch external flare fitting (Style 5) pressure element connection
• Compatible with standard non-corrosive refrigerants including R-12, R-22, R-134A, R-500, R-502, R-404A, and R-507
• Cast iron body construction with rust-resistant finish

This valve is ideal for HVAC and commercial refrigeration applications where automatic water flow regulation is required to maintain proper head pressure in water-cooled condensers, cooling towers, and similar systems. The pressure-actuated design eliminates the need for external controls, providing simple and reliable operation while improving system efficiency and extending equipment service life.
