Belimo B225HT731 Valve

The Belimo B225HT731 is a high-performance 1-inch NPT 2-way ball valve engineered for demanding hydronic and steam environments. Featuring a 7.31 Cv rating, this equal percentage flow valve ensures precise modulating control, critical for maintaining system stability. The forged brass body is paired with a 316 stainless steel ball and stem, providing the durability needed for low pressure steam applications up to 15 psi and high temperature hot water systems reaching 266°F. This HVAC control valve is compatible with up to 60% glycol solutions, making it a versatile choice for both heating and cooling loops. Designed for use with Belimo LR and AR series actuators, the B225HT731 provides reliable shut-off and high close-off pressure ratings. The blowout-proof stem and reinforced PTFE seats ensure long-term operational integrity in rigorous commercial mechanical systems.

• High Temperature Resilience: Rated for medium-temperature water and low-pressure steam up to 266°F.
• Precision Flow Control: Equal percentage characteristic prevents hunting in modulating control loops.
• Corrosion Resistance: Stainless steel ball and stem prevent pitting and scaling in harsh fluid conditions.
• Versatile Media Handling: Suitable for hydronic systems utilizing high glycol concentrations (up to 60%).
• Bubble-Tight Shut-Off: Ensures zero leakage, improving overall system energy efficiency and plant performance.
