This product is summed up many of the various electric actuator insufficient improvement, the latest products. Original German import, compact structure, reliable quality and superior performance. The main features are: 1, shell - the use of high-quality aluminum alloy, light weight. And inside and outside the surface by anodic oxidation treatment, the outer surface by powder coating ester, strong corrosion resistance. 2, the electrical - the use of SPG squirrel-cage motors, large torque output, and built-in thermal protection switch, temperature control, to prevent damage to motor. 3, manual structure - no power when the clutch lever can be pulled manually. Power, the clutch automatically reset. 4, position indicator - indicator installed on the center axis, the valve position can be observed. And light (SLU) to choose from. 5, dryer - used to control temperature, to prevent moisture condensation within the actuator to maintain the internal electrical components dry. 6, limit switch - to control by the cam mechanism, a simple adjustment of institutions to accurately and easily set the position. 7, torque switches (except outside GKQ-008) - to provide overload protection to prevent damage to motor. (Factory pre-set, please do not arbitrarily change the user settings). 8, self-locking - there are self-locking function to prevent the reversal, part of a stable and reliable transmission. 9, the installation - at the bottom of the installation in line with the ISO5211 international standard size, the drive sleeve can be removed in accordance with the need for processing, and adaptable. Can be mounted vertically, it can be installed level. 10, Terminal Blocks - compact line layout reasonable terminals diameter 2.5mm, pressure, solid connection. 11, the worm - the use of Au-round design, the contact surface with the worm, and torque transmission, and balance and wear-resistant, long service life. 12, PCU board - a compact and reasonable structure, the PCU board with a built-in chassis.
