ENG-93001-93621-08.04-1M • Printed in Switzerland • ZSD • Subject to technical modifications BC 4 NV.. actuators for valve nominal widths DN 15 - DN 80 Cost-effective turnkey solution Customers who choose Belimo motorized valves will be able to enjoy products that offer the same technically advanced standard and are as easy to use as the actuators for air control dampers for which the company has been famous for many years. AV.. actuators for valve nominal widths DN 65 - DN 150 High-performance AV.. linear actuators are available for all nominal widths from DN 65. They can likewise be supplied with different methods of control and with Multi-Function Technology (MFT). Manual operation for manual startup and emergency operation Cover made of impact-resistant plastic. Housing and bracket made of robust die-cast aluminum Also available on request with emergency control function (spring) in case of power failure Self-adaptation of valve stroke thanks to actuator intelligence (MFT types) Integrated position indication Automatic mechanical coupling of the valve stem to the actuator spindle 3-point or modulating control, variable with MFT types M20 union, IP54 guaranteed 1 m preassembled connecting cable with integrated terminals Available with Multi-Function Technology MFT® Complies with CE requirements MFT IP54 Multifunctionality The modulating NV24-MFT and AV24-MFT linear actuators feature the unique Multi- Function Technology MFT® from Belimo. There are numerous advantages, including: • The MFT electronics automatically detects the valve stroke and parameterizes the setpoints. • The individual parameters, such as the control signal, running time, position feedback, operating status indication etc., can be individually adjusted and adapted precisely to suit the requirements of the system when the equipment is installed. • The actuator monitors itself during operation and, on request, reports possible faults, such as a blocked stem or increased control path, directly to the supervisory control room. • MFT integrates an anti-blocking function. Dirt particles which could cause the actuator to stick are automatically removed. Slide switch for selecting the closing point and inverting signals Microprocessor-controlled brushless actuator with MFT functionality; prolongs the service life and reduces the noise level and current consumption Practical connecting terminals Electronic circuit of the NV24-MFT Status indication for a preliminary diagnosis of the actuator condition Microprocessor ASIC Pushbuttons for test and manual adaptation General information - linear actuators
