BELIMO R614AS+LFH230-S

When you’re specifying for demanding HVAC or industrial steam systems—such as boiler feed, heat exchanger bypasses or district‑heating loops—the R614AS+LFH230‑S stands out by combining precision valve control with a built‑in fail‑safe actuator. The valve body is rated for fluid temperatures from 0 °C up to 175 °C and can handle a close‑off differential pressure up to 1000 kPa—meaning it will reliably shut under heavy system loads. belimo.com+1 The rotating actuator has a torque of 4 Nm, 90° rotation, and completes the stroke in approx. 75 seconds in motor mode, with rapid spring return in under 20 seconds in a power‑off or fault condition. belimo.com For your integration work—whether in fire‑service systems, home‑automation or parking‑garage HVAC—you’ll appreciate a single device that handles both the valve and a resilient actuator, reducing number of components and simplifying installation. Compared to generic zone valves, this model adds high‑temperature capability, greater pressure rating and an actuator designed with auxiliary switch feedback and IP54 protection—offering a more robust, service‑friendly solution. The fail‑safe feature ensures the valve will move to its defined safe position on supply loss, enhancing system safety and reliability.
