Johnson Controls V47BD-3 Water Valve

The Johnson Controls V47BD-3 is a 1-inch temperature actuated modulating water valve designed for critical cooling and heating applications in HVACR and industrial systems. Built for performance and reliability, this Johnson Controls V47 series valve maintains precise temperature control by regulating the flow of water or glycol solutions. It features a broad 115-180 degree range and a standard 11/16" x 6" sensing bulb for accurate thermal response. This model is technically identical to the V47BD-3C, ensuring seamless integration into existing 1" NPT piping configurations. Designed without close-fitting sliding parts in the water passages, it effectively minimizes chatter and water hammer, protecting the integrity of the hydronic loop. The internal modulating water regulator mechanism is pressure-balanced to resist fluctuations in supply pressure, making it a rugged choice for service on heat exchangers, air compressors, and industrial printing machinery.

• Universal Compatibility: Direct replacement for Johnson Controls V47BD-3C with identical technical specifications and 1-inch pipe sizing.
• High-Performance Modulation: Provides smooth, modulating water flow control to achieve optimal equipment efficiency and water conservation.
• Rugged Design: Features a range spring that never contacts the process fluid, reducing corrosion risks and extending field life.
• Field Maintenance: Includes easy manual flushing capabilities to clear system debris without affecting the temperature setpoint.
• Versatile Application: Suitable for water or glycol-based systems, including internal combustion engine cooling and hydraulic oil heat exchangers.

What is the action of the V47BD-3 valve?
The valve is designed to open as the temperature at the sensing bulb increases, making it ideal for cooling applications requiring precise thermal modulation.

Can I use this valve for domestic drinking water?
No, this unit is constructed from copper alloys that contain lead and is intended only for industrial and HVACR non-potable water applications.

How do I adjust the opening point?
The setpoint is easily adjusted via the screw located at the top of the spring housing using a standard service wrench or screwdriver.
