When you need precise flow control in hydronic systems, the Belimo B318B valve is a robust choice. This 3/4" NPT, 3-way characterized control valve (CCV) is engineered for reliable performance in demanding HVAC applications. With a 7.4 Cv valve, it delivers accurate modulation for chilled or hot water systems, accommodating up to 60% glycol solutions within a 0-250°F (-18-120°C) fluid temperature range. The nickel-plated forged brass body, chrome-plated brass ball, and nickel-plated brass stem ensure durability and corrosion resistance. Its A-port provides equal percentage flow, while the B-port is modified for constant common port flow, making it ideal for air handling units, fan coil units, and VAV box re-heat coils. This hydronic control valve is designed for maintenance-free operation, offering a 600 psi body pressure rating and a 200 psi close-off pressure. Key Benefits: Precise Flow Control: Equal percentage flow characteristic on the A-port ensures accurate modulation for optimal system performance. Durable Construction: Forged brass body with nickel plating, chrome-plated brass ball, and nickel-plated brass stem for extended service life. Versatile Application: Suitable for a wide range of HVAC systems, including air handling units, fan coil units, and VAV re-heat coils. Wide Fluid Compatibility: Handles chilled or hot water and glycol solutions up to 60%. Robust Pressure Ratings: Designed for systems up to 600 psi body pressure and 200 psi close-off pressure. Common Questions: What is the application of Belimo B318B valve? This valve is typically used in air handling units on heating or cooling coils, fan coil unit heating or cooling coils, Unit Ventilators, VAV box re-heat coils, and bypass loops. It's suitable for hydronic systems with variable or constant flow. How to control flow with a 3-way ball valve in HVAC? The B318B utilizes a characterized disc to provide an equal percentage flow characteristic on the A-port, allowing for precise modulation of flow in mixing or diverting applications. Can Belimo B318B be used with glycol solutions? Yes, this valve is compatible with chilled or hot water, including solutions with up to 60% glycol.
