valve union lock system
Dual Block® is a patented system developed by FIP that allows you to lock the union nuts
of true union ball valves in a preset position.
The locking-nut device allows only the clockwise rotation of the nut on installation,
and prevent anti-clockwise rotation. When the valve has been installed
and the nuts have been tightened, the dual block system prevent the accidental loosening of these nuts:
the Dual Block® is particularly suited to hard working conditions where vibrations or thermal expansions
may affect the performance of ordinary true union valves.
