The Belimo Z2SU8M is a genuine S5 series spring return actuator, engineered for precise and reliable control of rotary valves in HVAC and water applications. This robust actuator delivers 8 Nm of torque and operates on AC/DC 24 V, supporting on/off, floating point, or DC 0-10 V control signals. It features a motor running time of 75 seconds and a spring return time of 20 seconds, ensuring safe and efficient operation with a maximum rotation angle of 95 degrees. With an IP54 protection class, it is suitable for various environmental conditions. It is commonly paired with 2-way control ball valves, such as the Belimo R6020R6P3-B1, which typically features a DN 20 nominal size, PN 6 pressure rating, 600 kPa maximum differential pressure, and a kvs value of 6.3 m³/h.
