Belimo B217 Valve

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.
