INSTALLATION
Before proceeding with installation. please follow these instructions carefully:
1) Check that the pipes to be connected to the valve are aligned in order to avoid
mechanical stress on the threaded joints.
2) Unscrew the union nuts (13) and slide them onto the pipe.
3) Solvent weld or screw the end connectors (7) onto the pipe segments.
4) Position the valve between the end connectors (fig. 6).
Warning: if a high pressure test is required, always position the body with the
"REGULAR" label upstream from the fluid direction.
5) Fit the union nuts on the valve body and manually tighten clockwise until they be-
come hard to turn; do not use wrenches or other tools that can damage the union
nut surfaces.
6) Extract the handle (12) from the valve body and extract its grey plug (1) (fig. 2)
7) Overturn the handle and insert in on the valve stem matching the handle teeth (A)
with the union nut teeth (B) (fig. 9-10).
8) Turn the handle counter-clockwise to fully tighten the union nut. The rotation
directions to tighten (TIGHTEN) and loosen (UNTIGHTEN) the union nuts are indi-
cated on the handle (fig. 11). Generally, if pipes are not oset, one turn is sucient
for correct tightening.
DISMOUNTING ASSEMBLY
1) Isolate the valve from the line (re-
lease the pressure and empty the
pipeline).
2) Fully unscrew the union nuts (13)
from the valve body and slide the
body out sideways (fig. 5-6).
To do this, we recommend you use
the Easyfit handle as a tool (fig. 9-10)
3) Before dismounting, hold the valve in
a vertical position and open it 45° to
drain any liquid that might remain.
4) After closing the valve, remove the
handle (12) (fig. 7) and insert the two
protrusions in the lower side in the
two apertures and in the carrier pas-
sage bore (8), extracting it by turning
counter-clockwise (fig. 8).
5) Press on the ball from the side oppo-
site the "REGULAR" label, being sure
not to scratch it, until the ball seat
carrier exits (8), then extract the ball
(5).
6) Press the stem (3) inwards until it ex-
its the body.
7) Remove the O-Rings (2, 6, 10) and
ball seats
(9) extracting them from
their seats, as illustrated in the ex-
ploded view.
1) All the O-Rings (2, 6, 10) must be in-
serted in their grooves as shown in the
exploded view.
2) Insert the stem (3) from inside the body
(4).
3) Place the ball seats (9) in the housings
in the body (4) and in the carrier (8).
4) Insert the ball (5) rotating it to the
closed position.
5) Screw the carrier (8) into the body and
tighten up in the clockwise direction us-
ing the handle (12) to limit stop.
6) Position the valve between the end con-
nectors (7) and tighten the union nuts
(13) clockwise using the Easyfit multi-
functional handle, being sure the socket
seal O-Rings (10) do not exit the seats.
7) Position the handle (12) on the stem (3).

Note: during assembly operations, it is
advisable to lubricate the rubber seals.
Mineral oils are not recommended for
this task as they react aggressively with
EPDM rubber.
