DesignArmed 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
YSPHA series pneumatic actuatorFeature1, 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 principle1,
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. Gear Box TypeRatioOutput(Torque
