BELIMO RB320+FRU230-3

The BELIMO RB320 + FRU230‑3 valve‑actuator package is designed to fulfil the needs of modern HVAC fan‑coil systems, offering a robust solution for precise water flow control. Thanks to its easy direct mounting onto RB‑series fan‑coil valves, installation becomes quick and straightforward — no complex assembly required, just a single screw. Once installed, the unit delivers tight sealing, minimizing the risk of leaks and ensuring reliable control of hot or chilled water through the system.

Its high close‑off pressure capacity allows it to handle demanding systems where pressure is significant — making it suitable for larger buildings or complex HVAC circuits. The FRU230‑3 actuator is designed for AC 230 V supply and consumes low power, helping reduce energy usage. Low operational noise adds to user comfort, especially in residential or office environments.

The integrated manual override knob gives technicians the flexibility to manually set valve position when needed — useful during maintenance or in case of power failure. Compared to cheaper generic valve actuators, the BELIMO solution stands out for durability, long life cycles and reliability under varying loads and pressures. Its solid construction and precision engineering mean fewer service visits and longer system life. For property owners or building managers, this translates into lower maintenance costs, stable performance and peace of mind that your HVAC system remains controllable and efficient.
