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 selectable control mode of Linear flow, Equal percentage, Linear rotation or Linear signal. The larger range of SM-valves are all designed for double flange connection. They are available in four different valve body sizes. All shall have snap connection for fast mounting of actuator.
