Belimo B231 Valve

The Belimo B231 valve is a robust 1 1/4" NPT, 2-way characterized control valve engineered for precise flow regulation in diverse HVAC hydronic systems. Featuring an equal percentage flow characteristic, this valve ensures stable and accurate control for heating and cooling coils. Its nickel-plated forged brass body, coupled with a stainless steel ball and stem, provides exceptional durability and corrosion resistance. With a 25 Cv rating, it's ideal for applications involving chilled or hot water up to 250°F (120°C) and glycol solutions up to 60%. This HVAC hydronic control valve is a reliable choice for air handling units, fan coil units, and variable air volume (VAV) box reheat coils, offering consistent performance and system efficiency. The 2-way ball valve HVAC design is built to handle a 400 psi body pressure rating and a 200 psi close-off pressure, making it suitable for demanding commercial and industrial environments.
