Description
The Belimo B310 is a precision-engineered 3-way ball valve designed for reliable flow control in chilled and hot water HVAC hydronic 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 commercial and industrial applications.
Key Features
- 3-way ball valve configuration for versatile mixing or diverting applications
- 1/2″ NPT connection for easy installation into standard piping systems
- 1.2 Cv flow coefficient for precise flow regulation
- A-port: Equal Percentage flow characteristic for accurate modulating control
- B-port: Modified flow characteristic for constant common port flow
- Nickel-plated forged brass body for superior corrosion resistance and long service life
- Stainless steel ball and stem for enhanced durability and reliable sealing
- Rated for chilled water and hot water applications up to 250°F maximum
Application
The Belimo B310 is ideal for use in commercial HVAC hydronic systems including fan coil units, air handling units, heat exchangers, and terminal units where precise 3-way flow control is required. Its dual flow characteristic design — equal percentage on the A-port and modified constant common port flow on the B-port — makes it well-suited for both mixing and diverting service in variable flow systems.
