Design
Armed with the idea of the small in volume, light in weight and novel in pattern, we designed and developed the XLHJ series gear operators which are wildly applied in the area of valve automation control. These kinds of products were specially designed used for butterfly valve, ball valve and plug valve together with K-Torc series pneumatic actuator.

Feature
1, Easy connection: There are two keyway apart 90°in the inner hole of worm gear so as to be convenient for customer to choose relative position between gear operator and valve.
2, Easy operating: Pull out the position pin and rotate off center device with 180°to realize pneumatic drive by positioning pin acted or to realize manual drive in the opposite way.
3, Dustproof and waterproof : The gear operator is filled with special lubricant before leaving the factory. It is solid sealed with valve after installation possessing dustproof and waterproof function with protecting grade IP65.
4, Many Output torques: It consists of a series of products, so output torque matches with all kinds of pneumatic devices and valves.

Operating principle
1, Assembling procedures: The bottom of gear operator should be connected with valve, bracket surface connected with cylinder (actuator), valve stem go through the inner hole of worm gear and the square on the end of stem matches with square hole of cylinder (actuator).
2, Operating procedures: The cylinder (actuator) drives valve stem and worm gear rotating together when pneumatic drive and worm shaft meshes with worm gear to drive valve stem rotating along with piston of cylinder (actuator) moving when manual drive. When pneumatic drive, pull out the pneumatic drive by worm gear rotating following with pneumatic valve stem. Just make the worm shaft mesh to realize manual drive.
