Description
Belimo B254 2″ NPT 2-Way Ball Valve Overview
The Belimo B254 is a heavy-duty 2-inch, 2-way ball valve engineered for precise flow control in demanding hydronic HVAC applications. Featuring a nickel-plated forged brass body paired with a stainless steel ball and stem, this valve delivers exceptional corrosion resistance and long-term durability in both chilled water and hot water systems.
Key Features
- 2-inch NPT end connections for straightforward installation into standard piping systems
- High flow capacity with a 240 Cv rating, supporting large-volume hydronic circuits
- 2-way configuration for reliable on/off or modulating flow control
- Equal percentage flow characteristic for accurate, stable control across the full valve stroke
- Nickel-plated forged brass body for superior strength and corrosion resistance
- Stainless steel ball and stem for extended service life and leak-free performance
- Rated for chilled water and hot water service up to 212°F maximum
- Compatible with glycol solutions up to 60% concentration
Application Suitability
The B254 is designed for commercial and industrial HVAC hydronic systems where precise temperature control is critical. Its equal percentage flow characteristic makes it ideal for variable flow applications such as air handling units, fan coil units, heat exchangers, and chiller/boiler piping circuits. The valve’s glycol compatibility ensures reliable operation in freeze-protection systems and cold-climate installations.
