Johnson Controls V47AE-2 Valve

The Johnson Controls V47AE-2 Valve is a cast iron direct-acting temperature actuated water regulating valve engineered for precise thermal management in commercial and industrial hydronic systems. This high-capacity 1 1/4" NPT valve features a heating point range of 115 to 180°F, making it a reliable solution for maintaining specific fluid temperatures in heat exchange applications. The V47AE-2 utilizes a Style 4 sensing bulb measuring 11/16" in diameter and 6" in length, connected by a 6-foot capillary for flexible placement away from the valve body. Its direct-acting configuration ensures the valve opens on a temperature rise, providing consistent flow modulation to prevent overheating. Built with a 1/2" NPT external fitting and rugged cast iron construction, this temperature actuated water valve is designed to handle the rigors of high-pressure mechanical rooms while ensuring long-term system stability and HVAC temperature control accuracy.

• Precise Modulation: The direct-acting mechanism provides accurate water flow regulation based on sensing bulb temperature.
• Industrial Durability: Rugged cast iron body construction withstands high-demand commercial environments.
• Flexible Installation: A 6-foot capillary allows for remote bulb placement in tanks or pipes.
• Standardized Connections: 1 1/4" NPT ports ensure compatibility with standard industrial piping.
• Wide Thermal Range: The 115 to 180°F range covers the majority of standard heating and process water requirements.

What is the difference between direct-acting and reverse-acting in the V47 series?
The V47AE-2 is direct-acting, meaning the valve opens as the temperature at the sensing bulb increases. This is typically used for cooling applications or to bleed off excess heat in a system.

Can the capillary be shortened if it is too long for my application?
No, the 6-foot capillary is a sealed component containing a specific volatile charge. Cutting or kinking the tube will cause the temperature actuated water valve to fail immediately.

What is the maximum water pressure rating for this valve?
This Johnson Controls water regulating valve is typically rated for a maximum water pressure of 150 psi, though you should verify specific head pressure requirements for your pump over 50 psi.
