DESCRIPTION The SM series is a range of self-balancing dynamic flow control valves that are pressure independent and 2-way and ready to accept digital or analog input signals. Each valve has an adjustable maximum flow rate setting to enable flow limitation to and balancing of the coil or zone which the valve is controlling. All SM actuators are microprocessor based with a self-calibrating feature. The SM actuator range includes standard incl. feedback, failsafe and BACnet. All SM actuators are programmable and with display. The SM actuators accept analog 0(2)10V DC or 0(4)-20mA as well as digital 3-point floating or 2-position input signals and work with control mode of linear flow or linear rotation. The smaller range of SM-valves are all designed for double union piping connection. They are available in two different valve body sizes with a range of end connections. All shall have snap connection for fast mounting of actuator. Tech note · FlowCon SM 15-40 mm / 1/2”-1 1/2” · march 2024 · www.flowcon.com Page 4 of 7
