Description
The Belimo B307 is a precision-engineered 3-way ball valve designed for reliable flow control in chilled and hot water HVAC systems. Built with a nickel-plated forged brass body and a stainless steel ball and stem, this valve delivers exceptional durability and corrosion resistance in demanding hydronic applications.
Key Features
- 1/2″ NPT connection for straightforward installation into standard piping systems
- 3-way configuration with A-port equal percentage flow characteristic for precise modulating control
- B-port modified flow characteristic engineered for constant common port flow, maintaining consistent system pressure
- 0.3 Cv flow coefficient suited for low-flow, precision hydronic control applications
- Nickel-plated forged brass body provides superior strength and corrosion resistance
- Stainless steel ball and stem for long service life and reliable sealing performance
- Rated for chilled water and hot water service up to 250°F maximum
Application
The B307 is ideal for use in commercial and light industrial HVAC systems where accurate flow balancing and temperature control are critical. The equal percentage A-port flow characteristic ensures smooth, stable modulation across the full range of valve travel, making it well-suited for fan coil units, air handling units, and other hydronic terminal equipment. The modified B-port characteristic maintains a constant flow rate at the common port, simplifying system design and improving overall hydronic balance.
