Johnson Controls V-4440-1002 Valve Assembly

The Johnson Controls V-4440-1002 is a professional-grade three-way brass valve assembly engineered for precise proportional control in pneumatic HVAC systems. Featuring a 1/2" connection size and a robust brass body, this unit is designed to regulate the flow of hot water, chilled water, or steam in terminal units like fan coils and induction units. It operates with a 4 to 12 psi spring range and provides a 2.4 Cv flow coefficient, ensuring stable performance across varying pressure drops. This assembly serves as the direct replacement for the V-4440-2, allowing for seamless integration into existing pneumatic architectures without extensive repiping. The inclusion of a factory-installed elbow connector simplifies field installation. Technicians favor this pneumatic water valve for its reliable mixing or diverting application capabilities and its high-quality construction which resists mineral buildup and ensures long-term seat integrity in demanding commercial environments.

Key Benefits for Technicians:

• Direct Interchangeability: Engineered specifically to replace legacy V-4440-2 valve assemblies without modification.
• Broad Compatibility: The 1/2 inch NPT brass body and standard pneumatic actuator interface fit most terminal unit configurations.
• Precise Flow Control: The 2.4 Cv rating and calibrated 4-12 psi spring allow for accurate modulation and improved system energy efficiency.
• Reduced Install Time: Comes equipped with a necessary elbow connector, reducing the need for additional small-bore pneumatic fittings.

Common Installation Questions:

Can this valve be used for both mixing and diverting service?
Yes, the V-4440-1002 is designed for three-way valve applications, making it suitable for bypass or mixing configurations in hydronic loops.

What is the maximum fluid temperature rating?
This brass HVAC valve is typically rated for saturated steam up to 15 psig or water up to 281°F, depending on the specific diaphragm and packing setup used in the pneumatic operator.

Does this assembly include the pneumatic actuator?
This part number refers to the valve body and linkage assembly with the elbow connector; verify your actuator requirements (such as the V-3000 series) separately based on your control signal.
