SLJ series gear operators

This series consists of eight models with the speed ratio varying from 26:1 to 520:1 and the toque ranging from 300NM to 22000NM. The torque difference between every two adjacent models is small, helping to save a lot of costs for customers when selecting a specific product. The clutch gear operator has a torque ranging from 300NM to 22,000NM and is available in 8 models with the speed ratio varying from 26:1 to 520:1.

Instructions for Installation and Operation

Connect the bottom side of the reducer to the valve and the bracket face to the cylinder. Then slide the valve shaft into the inner hole on the cylinder until the valve shaft end is well matched with the square hole of the cylinder on all four sides.

A tooth collision may occur when rotating the lever (by 180° outwards) to engage the worm. In such case, you need to turn the hand-wheel to a certain angle so that they can become engaged with each other.

Actuating the device through pneumatic and manual means simultaneously is not allowed.
