Description
The Belimo B323 is a heavy-duty 3-way ball valve engineered for reliable flow control in commercial chilled water and hot water HVAC systems. Built with a nickel-plated forged brass body and stainless steel ball and stem, this valve delivers long-lasting corrosion resistance and dependable performance in demanding hydronic applications.
Key Features
- 1″ NPT connection for straightforward installation into standard piping systems
- 10 Cv flow coefficient for precise, high-capacity flow control
- 3-way valve configuration for versatile mixing or diverting applications
- A-port: Equal Percentage flow characteristic for accurate modulating control
- B-port: Modified flow characteristic for constant common port flow, ensuring system balance
- Nickel-plated forged brass body for superior corrosion resistance and structural integrity
- Stainless steel ball and stem for extended service life in both chilled and hot water service
- Rated for chilled water and hot water applications up to 250°F maximum
Application
The B323 is ideal for use in commercial HVAC hydronic systems, fan coil units, air handling units, and terminal equipment where precise 3-way flow control is required. The equal percentage A-port characteristic provides excellent control linearity across the operating range, while the modified B-port maintains consistent flow at the common port — making this valve well-suited for variable-flow and constant-flow hybrid system designs.
