When you need precise flow authority in your hydronic systems, the Belimo B313B valve is a solid choice. This 1/2-inch, 3-way ball valve HVAC component is engineered for reliable performance in demanding applications. Featuring a 4.7 Cv, it's designed for accurate control of chilled or hot water, accommodating up to 60% glycol solutions, with a maximum fluid temperature of 250°F. The A-port delivers an equal percentage flow characteristic, while the B-port is modified for constant common port flow, ensuring stable system operation. Constructed with a nickel-plated forged brass body, a chrome-plated brass ball, and a nickel-plated brass stem, this valve is built to withstand a 600 psi body pressure rating and a 200 psi close-off pressure. Its NPT internal thread connection simplifies installation, making it ideal for air handling units, fan coil units, and VAV box re-heat coils. Key Benefits: Precise Flow Control: A-port equal percentage and B-port modified flow characteristics ensure accurate modulation. Robust Construction: Nickel-plated forged brass body, chrome-plated brass ball, and nickel-plated brass stem for extended service life. Wide Application Range: Suitable for chilled or hot water systems with up to 60% glycol, operating up to 250°F. High Pressure Rating: Handles up to 600 psi body pressure and 200 psi close-off pressure for system integrity. Versatile Compatibility: Integrates seamlessly into air handling units, fan coil units, and VAV box re-heat coils. Common Questions: What is the Cv rating for a Belimo B313B valve? The Belimo B313B valve has a Cv rating of 4.7, providing effective flow control for its specified applications. How to select a 3-way valve for HVAC? When selecting a 3-way ball valve HVAC, consider the Cv, flow characteristic (equal percentage, linear), media compatibility, temperature range, and pressure ratings to match your system's requirements. The B313B is a characterized control valve designed for mixing or diverting applications. What applications is the Belimo B313B suitable for? This valve is typically used in air handling units on heating or cooling coils, fan coil units, Unit Ventilators, VAV box re-heat coils, and bypass loops in hydronic systems with variable or constant flow. It is not suitable for use as a change-over valve. Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change.
