¢0. Fastening Plate
With the fastening plate for the ball valve type 546,
forces are absorbed which could occur during
valve operation (e.g. initial breakaway torque). In
implementing the fastening plate, working forces
are not transmitted to the piping system.
In piping systems which are subject to temperature
fluctuations, longitudinal or bending forces occur if
thermal expansion is hindered. So as not to impair
valve functioning, these forces must be absorbed
by the appropriate fixed points in front of or behind
the valve.
The fastening plate is available in two sizes for the
dimension range DN 10 to DN 50. Two screws to
fasten on the ball valve are included in the scope
of delivery.
