Johnson Controls V-4440-1001 Valve Assembly

The Johnson Controls V-4440-1001 is a robust 1/2-inch pneumatic three-way brass valve assembly designed for precise HVAC terminal unit control. This unit features a 1.4 Cv flow coefficient and is engineered for proportional control of hot water, chilled water, or 50% glycol solutions in mixing or diverting applications. The assembly operates on a 4 to 12 psi spring range, ensuring accurate modulation when paired with pneumatic controllers. Built with a high-quality brass body and stainless steel stem, it provides reliable fluid flow regulation in demanding commercial environments. As the V-4440-1001 direct replacement for V-4440-0001, this assembly facilitates a seamless retrofit without requiring extensive piping modifications. The inclusion of a factory-installed elbow connector simplifies field installation and reduces labor time for contractors. This pneumatic valve actuator assembly is a standard component for maintaining hydronic system efficiency and optimizing zone temperature stability.

Key Benefits for Contractors

• Drop-In Compatibility: Serves as the official V-4440-1001 replacement for V-4440-0001 models, maintaining existing center-to-face dimensions.
• Reliable Proportional Control: The 4-12 psi spring range allows for smooth modulation in various pneumatic control systems.
• Durable Construction: Features a rugged brass body and flare-end connections to prevent leaks and withstand consistent cycling.
• Efficient Installation: Comes equipped with an elbow connector, minimizing the need for additional fittings during replacement.
• Optimized Flow: The 1.4 Cv rating is specifically calibrated for low-flow terminal units, such as fan coils and induction units.

Common Questions

Can the V-4440-1001 be used for steam applications?
No, this specific brass valve assembly is rated for water and glycol solutions. For steam service, a valve with compatible packing and seat materials must be selected to handle higher temperatures.

Is this valve a mixing or diverting type?
The Johnson Controls V-4440-1001 is a versatile three-way valve that can be piped for either mixing or diverting configurations depending on the system requirements.

What happens if my controller signal exceeds 12 psi?
The 4 to 12 psi pneumatic spring will be fully compressed at 12 psi. While the actuator can handle higher pilot pressures, the valve will remain at its full stroke position until the signal drops back into the operating range.
