Johnson Controls V47AS-10 Valve

The Johnson Controls V47AS-10 is a heavy-duty, 2-inch temperature actuated modulating water valve designed for precision flow control in high-capacity refrigeration and cooling systems. Built for systems utilizing non-corrosive refrigerants, this pressure-actuated valve modulates water flow to maintain a constant temperature or pressure, ensuring optimal condenser performance. It features an adjustable range of 85-125 degrees Fahrenheit, making it a reliable solution for managing thermal loads in industrial heat exchangers. The assembly includes a 6-foot capillary and a 11/16" x 10" sensing bulb for accurate remote sensing. As a direct-acting valve, the V47AS-10 opens on a rise in temperature, facilitating efficient heat rejection. The 2-inch NPT connection and robust construction allow for high-volume bypass or cooling applications where maintaining a specific condenser water temperature is critical for compressor longevity and system efficiency.

Key Benefits

• Precision Modulating Control: Maintains stable setpoints by varying water flow based on real-time temperature fluctuations.
• Optimized Heat Exchange: Large 2-inch porting supports high GPM requirements for industrial-scale condensers.
• Versatile Application: Ideal for closed-loop cooling towers and water-cooled refrigeration units.
• Standardized Integration: The 11/16" x 10" bulb fits most standard thermowells for streamlined installation.
• Operational Stability: Reduces short-cycling of compressors by providing consistent head pressure control through water flow regulation.

Common Questions

How do I adjust the opening point on the V47AS-10?
The opening point is adjusted via the range spring adjustment screw located on the valve body; turning the screw modifies the tension to align with your required 85-125°F setpoint.

What media is this 2-inch water valve compatible with?
This valve is designed for use with water or glycol solutions; it is specifically engineered for non-corrosive applications in HVACR environments.

Does the V47AS-10 require an external power source?
No, this is a self-contained, temperature-actuated valve that utilizes the thermal expansion of the sensing element to modulate flow without the need for additional controllers or actuators.
