The H-type valve actuator is a worm reducer for 90 degree rotation, which is designed to be installed on large butterfly valves, etc. Helical gear attachments are standard for reducing input shaft torque. The 1-step reduction of helical gear accessories is used for electric, and the 2-step reduction is used for manual.


Product features:

▶  It can be used in combination with electric and pneumatic torque limiting SMB, JMB type, etc., and it can also be operated manually in combination with other manual reducers.

▶  The worm uses special steel, and the worm gear uses high tensile strength bronze, which makes it very hard. In addition, the gear accuracy has been improved to reduce the backlash.

▶  The stopper uses the stop screw method, which is easy to adjust and has excellent durability for all sizes.

▶  Each output torque is available in three sizes.
