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
The working medium should not contain particles ,corrosive gas or
liquid
