Johnson Controls V-4332-1009 Valve

The Johnson Controls V-4332-1009 is a high-performance 1/2 inch flare valve engineered for precision fluid control in HVAC terminal units and small air handling systems. This three-way mixing valve operates on a 4 to 8 psi spring range, allowing for seamless integration with pneumatic control systems. Designed with a 1.7 Cv PDTC port (Pressure Dependent to Close) and a 2.3 Cv PDTO port (Pressure Dependent to Open), it provides balanced flow characteristics to maintain linear room temperature control. The assembly features a robust brass body and stainless steel stem, ensuring durability when handling hot or cold water media. With its SAE 45-degree flare connections, this valve eliminates the need for soldering, simplifying field maintenance and replacement tasks for service contractors. The pneumatic actuator provides reliable modulation, making it a staple for maintaining occupant comfort while maximizing energy efficiency in commercial climate control applications.

• Efficient Mixing Logic: Specifically designed for 3-way mixing applications to regulate water temperature by blending return and supply streams accurately.
• Solderless Installation: The 1/2" flare connection allows for fast mechanical coupling to copper tubing, reducing labor time and site hazards.
• Wide Operating Range: Rated for static pressures up to 400 psig, making it suitable for high-rise building locations and demanding mechanical rooms.
• Reliable Stem Sealing: Equipped with standard non-adjustable ring packings for leak-free operation and extended service life in hydronic systems.
• Pneumatic Compatibility: Optimized for standard 1/8" NPT air port connections used in legacy and modern pneumatic control architectures.

Common Questions

Can the V-4332-1009 be used for steam applications?
This specific model is primarily designed for hot and cold water service. For steam applications, ensure you are using models with stainless steel trim and appropriate temperature ratings.

Does this valve require a specific mounting orientation?
As a three-way mixing valve, it must be piped so the two inlets blend into a single outlet. Refer to the flow directional arrows on the brass valve body to ensure proper PDTC and PDTO port configuration.

What is the maximum fluid temperature this valve can handle?
The unit is typically rated for water temperatures between 35°F and 281°F, though the synthetic rubber diaphragm in the actuator has an ambient limit of 150°F.
