V46AT-2C Johnson Controls Water Regulating Valve

Overview

The Johnson Controls V46AT-2C is a pressure-actuated, modulating water-regulating valve designed to control the flow of water or glycol to a water-cooled condenser in refrigeration systems. It acts directly to open as refrigerant pressure increases, helping to maintain stable head pressure.

Features

• Pressure-balanced design ensures the setpoint remains unaffected by sudden or gradual changes in water supply pressure.
• No close-fitting or sliding parts in the water passages, which minimizes hysteresis and prevents sticking caused by sediment or contamination.
• Free movement of all parts provides smooth pressure modulation and minimizes chatter or water hammer.
• Withstands high hydraulic shock without damage to the valve body or internals.
• Take-apart construction allows for easy manual flushing and inline disassembly without removing the valve from the system.

Specifications

• Nominal Valve Size: 2-1/2 inches
• Connection Type: 4-hole ASME Flanged
• Operating Pressure Range: 160 to 260 psi
• Body Material: Cast iron with a rust-resisting finish
• Pressure Connection: 1/4-inch external flare

Applications

• Designed for use in commercial refrigeration and HVAC systems utilizing standard, non-corrosive refrigerants such as R-22 and R-502.
• Ideal for regulating coolant flow in both open and closed water systems connected to water-cooled condensers.
