HYDAC International GSV Instrucciones De Servicio página 33

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 so that, in the
event of vibrations during operation or any
break in the pipes, it is held securely.
Procedure for installing the GMP
NOTICE
Torque for the GMP = 20 Nm
The GMP may only be installed using a hook
and pin wrench DIN 1810B, inserted into the
boreholes provided.
Do not use pliers or similar tools on the main
body (5) as there is a risk of damage.
DANGER
When removing installed parts, be prepared
for them to be expelled at great speed.
