Johnson Controls V47AE-13 Valve

The Johnson Controls V47AE-13 is a direct acting temperature actuated water regulating valve specifically engineered for HVACR systems requiring precise thermal management. This 1 1/4" NPT valve is designed to modulate the flow of water or glycol solutions to maintain stable operating temperatures in condensers, heat exchangers, and industrial processing equipment. Featuring a 40 to 85 degrees F cross ambient point range, the V47AE-13 ensures reliable performance even when the bulb temperature fluctuates above and below the bellows temperature. The rugged cast iron construction provides industrial-grade durability, while the pressure-balanced design prevents fluctuations in inlet water pressure from affecting the set point. Equipped with a 6' armored capillary and a Style 4 temperature bulb (11/16" diameter x 16 1/4" length), this water regulating valve includes a 1/2" NPT external fitting for secure immersion sensing. The V47 series promotes water conservation and system efficiency by providing smooth modulation without chattering or water hammer, making it a standard choice for temperature-actuated modulating water valves in high-demand environments.

• Precise Thermal Regulation: Modulates flow effectively to maintain consistent heat transfer across a wide range of cooling applications.
• Cross-Ambient Versatility: The specialized cross ambient point range allows for accurate control regardless of surrounding temperature variations.
• Industrial Durability: Robust cast iron body with corrosion-resistant internal components ensures long-term service life in harsh mechanical rooms.
• System Stability: Pressure-balanced design minimizes the impact of water pressure surges, protecting against hydraulic shock and system noise.
• Easy Integration: Includes an internal bypass option and a standard 1 1/4" NPT connection for straightforward installation into existing piping.

Does this valve open or close on temperature increase?
The V47AE-13 is a direct-acting valve, meaning it is designed to open as the temperature at the sensing bulb increases.

Can this valve be used with fluids other than water?
Yes, it is compatible with water and glycol solutions. However, it is not intended for use in potable water systems due to lead content in the copper alloy components.

How should the sensing bulb be oriented for the best performance?
For optimal accuracy, the capillary end of the temperature bulb should be positioned higher than the plugged end. If the bulb is installed horizontally, the "TOP" indicator marked on the bulb must face upwards.
