Johnson Controls V-4332-1004 Valve

The Johnson Controls V-4332-1004 is a three-way mixing pneumatic valve designed for precise flow control in HVACR hydronic systems. Built with a 1/2-inch flare connection, this brass body valve utilizes a 9 to 13 psi spring range to manage terminal unit transitions effectively. The unit features dual flow coefficients with a 1.0 Cv PDTC port (Pressure Dependent To Close) and a 1.5 Cv PDTO port (Pressure Dependent To Open), ensuring balanced performance during mixing applications. Engineered for compatibility with standard pneumatic actuators, it provides reliable modulation for chilled or hot water systems. The rugged construction resists de-zincification, maintaining seat integrity under varying thermal loads. For contractors handling pneumatic control valve replacement, this component ensures seamless integration into existing Johnson Controls pneumatic systems without the need for extensive piping re-configurations or specialized adapters.

Key Benefits

• Precise Modulation: The 9-13 psi spring range allows for accurate sequencing within multi-zone pneumatic loops.
• Optimized Flow Dynamics: Differential Cv ratings accommodate specific pressure drops across mixing ports for system stability.
• Durable Construction: High-grade brass body and flare connections prevent leaks and withstand standard commercial HVAC operating pressures.
• Field Serviceability: Designed for standard pneumatic maintenance protocols, allowing for straightforward actuator mounting and calibration.

Common Questions

What is the maximum fluid temperature rating for the V-4332-1004?
This valve is typically rated for water temperatures ranging from 35°F up to 250°F, depending on the specific actuator and packing assembly used.

Can this valve be used for steam applications?
No, the V-4332 series mixing valves are specifically engineered for water and glycol solutions; steam service requires a different internal trim and packing.

How do I verify the correct port configuration?
Ensure the supply lines are piped to the two inlet ports for mixing service, with the combined flow exiting the common port to the terminal unit.
