H Series

intro_img

The H series is a worm reduction gear for 90-degree rotation designed to be attached to large butterfly valves, etc. The standard type comes with a helical gear attachment to reduce the input axis torque. The one-stage speed reduction of the attachment is for electric, and two-stage speed reduction for the manual.

Characteristics

  • Can be used with electric and air type Limitorque SMB and JMB series, and could also be manually operated when combined with other manual reduction gears.
  • Special steel is used for the worm, and bronze with high tensile strength is used for the worm gear. It is therefore very sturdy for its size. Also, we have enhanced the accuracy of the gear and minimized the backlash.
  • A durable and adjustable stop screw is used for the stopper in all sizes.
  • We offer 3 types for each output torque.
