Watertown electric butterfly ZYS-20 ZYS-5. Yangzhou, China-ZY series of fine small part of the transition back to the electric actuator (the introduction of Japanese glory technology), supply ZYS-40 ZYS-60. Models ZY-05 ZY-10 ZY-20 ZY-50 ZY-60 ZY-100 ZY-200 ZYS-05 ZYS-10 ZYS-20 ZYS-40 ZYS-50 ZYS-60 ZYS-100 ZYS-200 ZYR-05 ZYR-10 ZYR-20 ZYR-40 ZYR-50 ZYR-60 ZYR-100 ZYR-200 ZYP-05 ZYP-10 ZYP-20 ZYP-40 ZYP-50 ZYP-60 ZYP-100 ZYP-200.1., Powerful (intelligent, proportional, switch-mode, all kinds of signal output type everything); 2. Small size (volume equivalent to only about 35% of similar products); 3. Light and pleasant (only about 30% of the weight of similar products left and right); 4. reliable key components (such as bearings and electrical components are imported brand-name); 5. nice (alloy shell, fine and smooth, and can reduce electromagnetic interference); 6. Precision wearable (worm output integration of special copper alloy forging axis, high strength, wear resistance); 7. hysteresis few small (worm gear output shaft integration, avoiding the linkage gap, high transmission accuracy); 8. Security Assurance (via voltage 1500V detection, F-class motor insulation, safe and secure); 9. supporting simple (single-phase power supply, external line is particularly simple, but also do 380V, DC power supply); 10. Easy to use (free fuel, free point inspection, waterproof rust, installed at any angle); 11. protection device (double limit, thermal protection, overload protection); 12. The multi-speed (full stroke time of 5 seconds, 10 seconds, 15 seconds, 30 seconds, 60 seconds, etc.); 13 . corrosion and rust (brackets, couplings, screws are made of stainless steel); 14. intelligent CNC (digital setting, highly accurate, self-diagnosis, a machine can); 15. integrated one (highly integrated intelligent control module for electric device body, no external locator).
