Actuators for small valves

Electronic actuator used for the modulating control of room temperature and extract air temperature in various water-based applications with 2/3″ directional control valves 

• Electronic actuator with Modbus interface
• LED for indicating the operating status
• DIP switches for setting the communication parameters
• Display of actual values, setpoint values and status via Modbus
• Automatic closing point detection and valve calibration
• Modulating control of the control signal and hence of the valve position (0 – 100%), feedback via Modbus
• Automatic valve anti block function prevents the spindle from blocking if the valve remains idle for a prolonged period of time
• Automatic flushing
• Analogue inputs (can be configured) for two temperature sensors
• Automatic leak detection based on the flow and return temperatures
• Spindle without a spring, hence low wear, for exact positioning
