3.5 Mounting
Procedure for installing the GSV
NOTICE
Torque for the GSV = 80 Nm
The GSV must only be tightened on the
hexagon provided (11).
Do not use pliers or similar tools on the main
body (5) as there is a risk of damage.
It is forbidden to undo the glued hexagon
connection (11) from the valve body (5), since
this would inevitably alter the setting of the
device.
It is forbidden to remove the lead seal (2) and
the cap (1) and consequently to unscrew the
components because in so doing the setting of
the device would be altered and the GSV would
lose its approved status.
DANGER
When removing installed parts, be prepared
for them to be expelled at great speed.
Danger of fatal injury.
When installing, proceed as follows:
– Inspect the GSV visually.
– Remove the screw plug (13).
– Clean the sealing surfaces.
– Screw the GSV with the seal ring (12)
directly onto the pipe, or the adapter.
– When tightening the GSV on the connection,
the spanner must only be placed on the
hexagon provided (11).
– The GSV must be installed securely to
withstand vibrations during operation or any
break in the connection lines.
3.3 Cross-sections
The cross-section of the pipe on the feed-line
side must not be smaller than the cross-section
of the safety equipment inlet (10 mm).
GSV :
The pressure drop in the pipe on the feed-line
side must not exceed 3 % of the pressure
differential between the response pressure and
the back pressure for the max. mass flow rate.
Back pressures on the outlet side which affect
the cracking pressure and the cracking forces
or the mass flow rate must be taken into
account.
3.4 Installation
The warning notices given in Section 1.
"General information" must be followed.
On bladder accumulators, unscrew protective
cap (S) and seal cap (H) and remove
O-ring (O). Unscrew the gas valve insert (E)
completely using a valve extractor tool.
Please read the operating instructions!
