The device is a manual device directly installed on multi turn valves such as gate valve,track ball valve and stop valve.The device adopts the combination of spiral bevel gear and plane thrust bearing.The built-in valve stem nut adopts the lower structure,which is directly connected with the bevel gear disc,and bears
thrust and axial force up and down.The secondary transmission adopts the combination of straight tooth reducer,and the speed ratio can be adjusted according to the needs of users.It has the advantages of stable operation,large torque,low noise and high efficiency.The protection grade of conventional products isIP65.Under special circumstances,it can be used as IP67,IP68 or submerged underwater.Handwheel and valve stem cover can be customized according to
user requirements
