Description
The Belimo B225HT731 is a high-performance 2-way ball valve engineered for demanding hydronic and steam applications where standard valves fall short. Built with a brass body and stainless steel ball and stem, this valve delivers exceptional durability and corrosion resistance in high-temperature water systems up to 266°F (130°C) and low-pressure steam environments.
With a 1″ NPT connection and a 7.31 Cv flow coefficient, the B225HT731 provides precise equal percentage flow characteristics, making it ideal for modulating control in HVAC hydronic systems, fan coils, heat exchangers, and terminal units. Its compatibility with glycol solutions up to 60% concentration adds versatility for freeze-protection applications in commercial and industrial settings.
Designed to pair with Belimo actuators, this valve is a reliable choice for building automation and energy management systems requiring accurate, repeatable flow control.
