Electric motor actuator for lifting valves
Schubert & Salzer has developed its own lift drive for the sliding gate valves, seat valves and 3-way valves. The compact 2032 electric motor actuator has an actuating power of 800 N. With a standard dead band setting of only ±0.6 % of the entire stroke, the motor actuator achieves a repeat accuracy of up to ±0.3 %. It is offered in two versions: an open/closed version and a regulating drive version. Furthermore, it also offers safety functions that can be individually defined. For this purpose, the monitoring of the lifting force, the target value, the temperature of the electronics, etc. are integrated in the drive. For diagnostic purposes, the motor and overall operating period as well as the temperature and lifting ranges are all recorded. These diagnostic functions can be retrieved directly via the Device Config software. At the same time, this software tool gives users of regulating drives the opportunity to adapt parameters such as the actuating time, characteristic curve, signal range and limit switch positions to the process conditions. The 2032 motor actuator has an Ingress Protection rating of IP 65 as standard. The electric drive can also be optionally secured against power failures. In order to reset this zero voltage, the condensers store sufficient energy to ensure that the fitting moves into a defined fail-safe position if the supply voltage fails.
