Worm gears and worm gear teeth distribute tooth thickness according to materialstress, providing greaterload-bearing capacity,wear resistance, and extendingservice life.

Using the shortest worm support span to reduce worm deflection and improvetransmission efficiency.Separated rolling bearings are installed to avoid powder damage to the rolling bearingscaused bylong-term operation of the worm gear.The detachable involute spline drive sleeve can be assembled at any 90 degree.regardless of the position of the valve stem key.The entire series of worm gears are right-handed and standardized.Optional dual speed variable speed operation, meeting the requirement of 100 turnsof valve full stroke opening operation.The entire series offers lockable handwheels.The mechanical limit can be adjusted from 0 to 90 degrees + 5 degrees.Adjustable manufacturing error for valve closure components or transmission chains.for large errors, rotate one or more spline teeth; for small errors, directly adjust theswitchindicator panel.Align the switch pointer.The output flange shall comply with the provisions oflSO 5211. We can provide flatkeys, square keys, diagonal square heads, parallel square heads, flat heads, andspline connections.
