BELIMO R3050-58-S4+SR24-SR

The Belimo R3050‑58‑S4 + SR24‑SR valve‑actuator set delivers a versatile and high‑performance solution for water flow control in HVAC, chilled water plants, hydronic heating loops, or building mechanical systems. Thanks to its 3‑way ball‑valve design with a large DN 50 bore and a high flow coefficient (kvs 58 m³/h), it handles large volume flow — ideal for main risers, central piping loops, or big AHUs/plant rooms. The internal ball and seat design ensures smooth, reliable flow regulation whether directing water to one branch, mixing flows, or diverting them as needed.

The integrated actuator (SR24‑SR) drives the valve via control signals — enabling automatic adjustment from a Building Management System (BMS) or HVAC controller. This automates distribution of hot or chilled water, enabling zone control, energy-efficient load distribution, and responsive system management. The valve’s compatibility with water or glycol mixtures (up to 50%) and fluid temperatures from –10 °C to +120 °C make it suitable for a wide range of applications — from chilled‑water cooling to hot-water heating or mixed systems.

Its bubble‑tight sealing on the control path (A‑AB) prevents leaks and ensures system integrity, while the brass valve body and stainless internal components guarantee durability and corrosion resistance. The actuator’s IP54-rated housing protects against dust and splashes, so the unit works reliably in mechanical rooms, basements, or humid environments. Compared to generic valves or mismatched valve‑actuator combinations, this Belimo set offers a factory‑matched, professionally engineered package — reducing installation complexity, ensuring compatibility, and delivering long-term, robust performance with minimal maintenance.
