For precise hydronic system control, the Belimo B217 valve is a robust 2-way characterized control valve (CCV) engineered for demanding HVAC applications. This 3/4" NPT valve features an equal percentage flow characteristic, ensuring stable and accurate modulation of chilled or hot water, including solutions with up to 60% glycol. Its nickel-plated forged brass body, coupled with a stainless steel ball and stem, provides exceptional durability and corrosion resistance. With a 4.7 Cv rating and a 200 psi close-off pressure, the B217 is ideal for air handling units, fan coil units, unit ventilators, and VAV re-heat coils. It handles fluid temperatures from 0°F to 250°F and boasts a 600 psi body pressure rating, making it a reliable component for variable flow hydronic systems. Key Benefits: Precise Flow Control: Equal percentage characteristic ensures stable and accurate modulation for optimal system performance. Durable Construction: Nickel-plated forged brass body with stainless steel trim offers longevity in challenging HVAC environments. Wide Application Range: Suitable for chilled or hot water systems, including those with up to 60% glycol, across various HVAC units. High Close-Off Capability: 200 psi close-off pressure prevents leakage and ensures tight shut-off. Optimized for Hydronic Systems: Designed for variable flow applications, enhancing system efficiency and control. Common Questions: What actuators are compatible with the Belimo B217? This valve is designed for use with Belimo non-fail-safe (TR, LRB(X), LRQB(X), NRB(X) N4) and spring return (TFRB(X), LF) actuators, which are sold separately. Can this valve be used with glycol solutions? Yes, the B217 is rated for use with chilled or hot water applications containing up to 60% glycol solution. What is the maximum operating temperature for this valve? The valve can handle fluid temperatures ranging from 0°F to 250°F (-18°C to 120°C). How does the equal percentage flow characteristic benefit my system? This characteristic provides enhanced control stability, preventing control loop "hunting" and extending the lifespan of both the valve and actuator.
