Description
The Belimo B220HT731 is a high-performance 2-way ball valve engineered for demanding hydronic and steam applications where standard valves fall short. Built with a robust brass body and a stainless steel ball and stem, this valve delivers reliable, long-lasting service in high-temperature water systems up to 266°F and low-pressure steam environments. Its compatibility with glycol solutions up to 60% makes it an ideal choice for freeze-protected hydronic heating systems.
Key Features
- 3/4″ NPT end connections for straightforward installation into standard piping systems
- 7.31 Cv flow coefficient for precise, efficient flow control
- 2-way configuration for on/off or modulating flow control
- Equal percentage flow characteristic for accurate, linear control response across the full valve stroke
- Brass body construction for corrosion resistance and durability
- Stainless steel ball and stem for enhanced strength and resistance to high-temperature media
- Rated for high-temperature water applications up to 266°F (130°C) maximum
- Suitable for low-pressure steam applications
- Compatible with glycol solutions up to 60% concentration
Applications
- Commercial and industrial hydronic heating systems
