90 Degree Rotation Manual Operated Worm Gear Actuator

High transmission efficiency is one of the benefits offered by the JMG series worm gear actuator manufactured by Zhejiang Jimai Auto-tech Co.,Ltd. Additionally, this actuator features a self-locking construction that is stable. It is possible for users to alter the speed ratio according to their actual conditions of use. Moreover, the JMG worm gear actuator is capable of achieving a rotation of ninety degrees, which makes it suitable for use in a variety of quarter turn valves, including butterfly valves, ball valves, and others. JMG series worm gear actuator uses a shaft made of 40cr material, which has a higher level of strength than other materials. In addition, the surface has been subjected to carbonization treatment, which has significantly enhanced the overall strength and ensured that it will be able to function effectively in the harshest of working conditions. Through the utilization of our gearbox, it is possible to create valve control that is both more precise and more comfortable.

    Product Features
