Description
In modern HVAC systems—such as fan-coil units, VAV boxes or zone control applications—precision and reliability of flow control are critical. The BELIMO Z220S-230 fills this need by combining a two-way ¾″ valve body (DN20) with an integrated 230 V AC actuator and spring-return mechanism. This ensures that in case of power loss the valve will return to its safe “closed” state automatically. With a Kvs of 2.2 m³/h it offers appropriate flow for moderate zone loads, reducing the risk of oversizing and enabling better control. The valve body is forged brass, spindle nickel-plated brass, providing long service life and strong resistance to corrosion. It handles both chilled and hot water, including mixes of glycol up to 50 % by volume. Compared to alternatives which may lack spring return, have plastic bodies, or require external actuator mounting, this unit offers a fully integrated, maintenance-free solution. For your fire-service, home-automation or parking ventilation systems via MSI Agency, the Z220S-230 presents a trustworthy, low-energy, high-quality zone valve that supports modern building automation with fewer parts, less installation complexity and greater reliability.
