The Double Union Ball Valve Threaded proper installation is important for preventing leaks and ensuring a long service life.

The pipeline must be flushed to remove debris before installation to prevent damage to the ball and seats.
For solvent weld models, care should be taken to prevent solvent cement from contacting the ball or valve seats.
For threaded models, union nuts should be tightened by hand to avoid damage.
The valve can be installed in any orientation and should be in the open position during pressure tests.
