Belimo B221B Valve

This Belimo B221B valve is a robust 2-way ball valve engineered for precise flow control in demanding HVACR applications. Featuring a 3/4" NPT internal thread connection and a 24 Cv rating, this valve delivers an equal percentage flow characteristic, crucial for stable system operation. Its construction includes a nickel plated forged brass body, a chrome plated brass ball, and a nickel plated brass stem, ensuring durability and resistance to corrosion. Designed for use with chilled or hot water, it handles fluid temperatures from 0°F to 250°F and is fully compatible with solutions containing up to 60% glycol. With a body pressure rating of 600 psi and a 200 psi close-off pressure, this hydronic control valve is ideal for air handling units, fan coil units, unit ventilators, VAV box re-heat coils, and bypass loops in variable flow hydronic systems.
