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) from the body (7) and insert them in the pipe seg-
ments.
3) Solvent weld or screw the end connectors (12) onto the pipe segments.
4) Position the valve between the end connectors (fig. 8).
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 tighten clockwise (fig. 7).
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 (7) (fig. 7-8).
3) Before dismounting, hold the valve in
a vertical position and open it 45° to
drain any liquid that might remain.
4) Open the valve.
5) Remove the ball seat carrier (11) us-
ing the Easyfit quick release handle
(2). Extract the handle from the
central hub (15) pushing towards the
hub hinge centres (fig. 5-6). Insert
the two protrusion at the top of the
handle in the carrier seats (11) and
unscrew, extracting it by turning
counter-clockwise (fig. 9-10).
6) Press on the ball (6) from the side
opposite the "REGULAR" label, being
sure not to scratch it, until the ball
seat exits (11) then extract the ball
(6).
7) Remove the central hub (15) firmly
sliding it off the stem (4). Press the
stem inwards and extract it from the
body and remove the anti-friction
disk (16).
8) Remove the O-Ring (3, 8, 9, 10) and
ball seats (5) extracting them from
their seats, as illustrated in the ex-
ploded view.
1) All the O-rings (3, 8, 9, 10) must be
inserted in their grooves as shown in
the exploded view.
2) Place the anti-friction disk (16) on the
stem (4) and insert it in the body (7).
3) Place the ball seats (5) in the hous-
ings in the body (7) and in the carrier
(11).
4) Insert the ball (6) rotating it to the
closed position.
5) Screw the carrier (11) into the body
and tighten up in the clockwise direc-
tion using the handle (2) to limit stop.
6) Place the central hub (15) on the stem
(4) firmly pressing down to match the
internal hub key with one of the two
seats on the stem.
7) Position the valve between the end
connectors (12) and tighten the union
nuts (13) clockwise making sure the
socket seal O-Rings (10) do not exit
the seats (fig. 7-8).
8) Reposition the handle (2) on the
central hub (15) making sure the two
grooves in the central handle bore
match the two grooves on the side of
the hub and slightly press down until
the two hinges click.

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.
