Installation instructions:

1.For pipe thread connection type check valve,we should make sure the pipe being vertical against the surface of the valve body when tighten the connection part. our special warning is that we should only wrench the octagonal at the same end of body instead of the other side to avoid deformation so as to affect its normal open function.
2.For internal thread type check valve,we should control the lread 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
3.When connecting the pipe thread type check 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 4.thread,otherwise it will cause leakage due to loose connection.
When installing the pipe thread type check 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 check valve handle is parallel to the body,it is open,otherwise,it is close
