ASSEMBLY
-
Handle with care;
-
Place the valve between the flanges of the pipe and install the seal between the pipe and valve
flanges. Check that the seals have been positioned correctly. The distance between the counter
flanges must be the equal to the valve’s face to face distance. Do not use bolts of the counter flanges
to bring the piping close to the valve. The bolts should be cross tightened;
-
Do not weld the flanges to the piping after installing the valve;
-
Water hammers might cause damage and ruptures. Inclination, torsions and misalignments of the
piping may subject the installed valve to excessive stresses. It is recommended that elastic joints be
used in order to reduce such effects as much as possible;
-
Use belts and safety hooks for harnessing and lifting (see picture 1).
This valve is unidirectional: install in accordance with the flow direction arrow indicated
on the body.
Piping with vertical upstream flow: install the valve as shown in figure 3.
Piping with horizontal or inclined flow (upstream flow): install the valve as shown in figure 4.
