Johnson Controls V-4440-1011 Valve Assembly

The Johnson Controls V-4440-1011 is a robust three-way brass valve assembly specifically engineered for fan coil unit return valve applications and terminal unit control. This assembly features a 1/2-inch NPT connection and a 2.4 Cv flow coefficient, ensuring precise volumetric control in hydronic systems. Operating on a 6 to 9 psi spring range, the pneumatic actuator provides reliable modulation for mixing or diverting service. As the direct V-4440-0011 replacement, this unit maintains the same footprint for seamless field retrofits without piping modifications. The brass body construction resists scale buildup and corrosion, while the included straight connector simplifies the installation process for field technicians. High-temperature packing allows this valve to handle hot water or chilled water cycles effectively, maintaining tight shut-off and consistent pressure drops across the coil. Designed for longevity in demanding commercial HVAC environments, the V-4440-1011 ensures stable room temperatures and optimized pump energy consumption.

• Direct Retrofit Compatibility: Engineered as a drop-in replacement for V-4440-0011, eliminating the need for extensive re-piping during maintenance cycles.
• Durable Brass Construction: High-grade brass body provides superior resistance to dezincification and mechanical wear in closed-loop hydronic systems.
• Precise Actuation: The 6-9 psi spring range allows for accurate sequencing with other pneumatic components in a control loop.
• Optimized Flow Dynamics: A 2.4 Cv rating provides the ideal balance between flow capacity and authority for 1/2-inch terminal unit applications.
• Complete Assembly: Includes a factory-configured straight connector, reducing field assembly time and potential leak points.

Is the V-4440-1011 compatible with older pneumatic controllers?
Yes, this assembly works with standard 0-15 psi or 0-20 psi pneumatic signals, specifically calibrated for the 6 to 9 psi sequencing range common in Johnson Controls pneumatic systems.

Can this valve be used for both mixing and diverting?
While primarily used in return valve applications for fan coils, the internal plug design and three-way configuration allow it to be piped for specific mixing or diverting requirements depending on system design.

What is the maximum fluid temperature for this brass valve?
This HVAC pneumatic valve is typically rated for standard hydronic temperatures up to 281°F, making it suitable for both chilled water and low-pressure hot water systems.
