YZ-SS series quarter-turn worm gearbox suitable for ball valves, butterfly valves, plug,etc. Handwheel can be customized.
YZ-SS series quarter-turn worm gearboxes use worm and worm wheel revolute pairs, with high performance tapered roller bearing assembled on both ends of the worm shaft. It ensures the thrust requirement during rotation. It's in high mechanical efficiency, easy to operate. This product can switch two ratios at will. When opening and closeing the valve, you can use the high ratio to output high torque to open and close the valve. When the pressure is relieved, you can use the low ratio to operate the valve quickly.
These gear operators are well suited for applications in waterworks, chemical, power, HVAC and most general industrial applications.
