Installation of 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.
