product description
A manual device
An overview of the
The reducer can be used in combination with the pneumatic device to realize manual or pneumatic drive for 90 degree open butterfly valve and plug valve.
The main features
1. Small size, light weight, reasonable design and novel style;
2, product serialization, output torque and pneumatic device, various valve matching.
3. The worm gear connection inner hole has two keyways separated by 90 degrees, so that users can select the relative position of the device and the valve body according to their needs.
4, can freely switch between manual and pneumatic: lifting limit pin, rotating eccentric device 180 degrees, automatic limit pin limit, pneumatic; Conversely, the implementation of manual;
5. When the product leaves the factory, it is equipped with a special grease. After assembly with the valve, it is sealed, dustproof and waterproof.
6. Protection is IP65.
Directions for use
The bottom surface of the reducer is connected with the valve, the support surface is connected with the cylinder, and the valve shaft is also connected with the inner hole of the worm wheel. The four sides of the valve shaft end are matched with the square hole of the cylinder. (working process: when pneumatic, the cylinder drives the valve shaft and the worm wheel rotates together. When manual, the worm meshes with the worm wheel to drive the valve shaft to rotate and the cylinder piston also follows.
Two, turn the handle (external rotation 180 degrees) on the closing worm, will appear the handle tooth phenomenon, need to turn a handwheel Angle can close.
Three, there are three kinds of gear reducer bracket cover, users can choose according to the needs of different types of cylinder configuration.
Four, pneumatic and manual can not be driven at the same time.
