Belimo B313B Valve

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.
