The SLSVG Nucom type angular stroke electric actuator is assembled with the UNIC actuator from Japan's Koei Corporation and the SLSVG servo measurement control box developed and invented by our company. In addition to possessing all the excellent performance of our company's SLSVG servo measurement control box, it can achieve mutual isolation of power supply, input signal, and position feedback without increasing the size and appearance. Therefore, it can be directly connected to the AI/AO ports of computer systems from different manufacturers, avoiding common ground interference and common ground short circuit, saving signal isolators in the system, and improving cost-effectiveness. It can easily form an electronic control valve with the angular stroke regulator valve body, and can directly drive the air door baffle, etc.
