Description
The MB3-SC-24M Ball Valve Actuator is a compact and efficient actuator solution designed for use with VB200R, VB210R, VB300R, and VB310R valve ranges. Its innovative Pop-Top connection system enables simple, tool-free mounting and secure installation, ensuring reduced setup time and improved reliability.
Engineered for proportional (modulating) control, the actuator supports both 0–10 V DC and 4–20 mA DC analogue input ranges, making it highly adaptable for a variety of HVAC and fluid control applications. In case of power failure, the spring return function ensures that the actuator closes the valve, providing an additional safety measure.
With a robust design, IP31 protection rating, and the ability to operate within a wide ambient temperature range (0–60 °C), the MB3-SC-24M is suitable for demanding environments. Convenient features such as terminal block connection, removable cable gland, and a visible position indicator enhance usability and serviceability.
