V47AC-40C Johnson Controls MODULATING Valve

Overview

The Johnson Controls V47AC-40C is a 2-way, 3/4-inch temperature-actuated modulating water valve designed to regulate the flow of water or glycol to maintain a desired temperature. It features a cross-ambient design that operates efficiently within a specified temperature range, providing smooth modulation and stable temperature control for various commercial applications.

Features

• Pressure-balanced valve design ensures setpoint is independent of water inlet pressure.
• No close-fitting sliding parts in water passages to reduce fouling and prevent stuck valves.
• Range spring is isolated from the water to prevent corrosion and sedimentation.
• Valve design minimizes chatter and water hammer for quieter operation.
• Allows for easy manual flushing to clear debris when necessary.

Specifications

• Pipe Size: 0.75 inches (3/4″ NPT Threaded)
• Temperature Range: 40 to 85°F
• Capillary Length: 6 feet with Nylon Armor
• Bulb Dimensions: 11/16 inch diameter x 10 inches length (Style 4)
• Maximum Water Temperature: 170°F
• Maximum Supply Water Pressure: 150 psig
• Body Style: Two-Way Forward Acting

Applications

• Regulating water or glycol flow in commercial HVAC and refrigeration systems.
• Engine cooling systems to maintain exchanger flow for stable operating temperatures.
• Compressor systems to control circulating water and balance discharge heat.
• Hydraulic equipment to regulate coolant and prevent overheating of hydraulic oil.
