Installation manual
?
For pipe thread connection type ball valve,we should make sure the pipe being vertivcal against the end surface of the valve body when tighten the connection part.our special warning is that we should only wrench the octanal
At the same end of body instead of the other side to avoid deformation so as to affect its normal open function.
For internal thread type ball valve,we should control the length of the external thread at the pipe end in case deformation of the valve body caused by the external thread’s aqueezing the surface of the internal thread so as to affect leakproofness
When connecting the pipe thread type gate valve with pipe thread,the internal thread can be either tapered pipe thread or cylindrical pipe thread,but the external thread must be tapered pipe thread,otherwise it will cause leakage due to loose connection
When installing the pipe thread type ball valve,the sealing material must be clean.
Such obstacles as wall,coupling nut and pipe should not be placed inside the open/close range
When the ball valve handle is parallel to the body,it is open,otherwise,it is close
?
Application
?
The ball valve is mainly used for cutting off,distributing and changing the direction of the flow medium in the pipeline,to prolong the service life of the ball valve,full open and full close are highly suggested
?
Competitive Advantage:
?
1. Small resistance with the fluid
2. Small force is needed when open and close the valve
3. Unlimited by the direction of flow medium
4. Resistance between the working medium and the sealing surface is smaller than that of stop valve’s when the valve is opened completely
we can copperate with customer to build a warehouse with mutual benefit, save the purchase time
