V46AE-12C Johnson Controls Regulating Valve

Overview

The Johnson Controls V46AE-12C is a commercial V46 Series pressure-actuated water-regulating valve designed to control the flow of water or glycol to water-cooled condensers in response to refrigerant head pressure changes. It features a direct-acting modulation that opens on a pressure increase, helping to maximize cooling system efficiency and minimize water waste.

Features

• Pressure-balanced design that maintains a consistent setpoint despite water pressure fluctuations.
• Self-contained, non-electric operation powered directly by refrigerant circuit pressure.
• No close-fitting or sliding parts in water passages, which minimizes chatter, water hammer, and potential sticking from debris.
• Accessible range spring that allows for straightforward adjustment and manual flushing without altering the core setup.
• Robust construction allowing for inline serviceability and part replacement.

Applications

• Automatically modulating water or glycol flow to water-cooled condensers in refrigeration systems.
• Ideal for integration with commercial ice machines, ice cream machines, and refrigeration cases.
• Suitable for environmental regulation in computer room air conditioning units.
• Used across industrial and commercial HVAC systems, cooling towers, and chiller water loops.
