Belimo B317B Valve

For the discerning contractor, the Belimo B317B Valve is a robust 3-way ball valve engineered for precise flow control in demanding HVACR hydronic systems. This Characterized Control Valve (CCV), with its 3/4" NPT internal thread connection, delivers a reliable 4.7 Cv, making it ideal for managing chilled or hot water, even with up to 60% glycol solutions. Its nickel-plated forged brass body, chrome-plated brass ball, and nickel-plated brass stem are built to withstand fluid temperatures from 0°F to 250°F and body pressures up to 600 psi. The A-port provides equal percentage flow, while the B-port is modified for constant common port flow, ensuring stable and accurate regulation across various applications. This valve is a solid choice for air handling units, fan coil units, unit ventilators, VAV box re-heat coils, and bypass loops, offering consistent performance in both variable and constant flow systems.
