YJ-SS series part-turn worm gearbox adopts the structure of worm gear and spur gear reducer, with high output torque and low noise and stable operation. The two speed ratios can be switched at will. When opening and closing the valve, you can use a high speed ratio to output high torque to open and close the valve.
