Belimo B312 Valve

For the contractor needing reliable flow management, the Belimo B312 Valve is a robust 3-way characterized control valve engineered for demanding hydronic applications. This 1/2" NPT valve, featuring a 3.0 Cv, is constructed with a nickel-plated forged brass body and a durable stainless steel ball and stem, ensuring longevity in diverse environments. It's specifically designed for precise control of both chilled water and hot water systems, handling fluid temperatures up to 250°F and glycol solutions up to 60%. The A-port provides an equal percentage flow characteristic, while the B-port is modified for constant common port flow, optimizing system performance. Ideal for integration into air handling units, fan coil units, Unit Ventilators, VAV box reheat coils, and bypass loops, this valve maintains a 600 psi body pressure rating and a 200 psi close-off pressure, making it a dependable component for variable or constant flow hydronic systems.
