7.7.3 Hydraulic connection of the valve
CAUTION
Damage of the valve
During operation, hydraulic lines and hoses installed under mechanical stress
create additional mechanical forces, which reduce the life cycle of the valve and the
complete machine or system.
▶
Assemble lines and hoses without stress.
1.
Depressurize the relevant system part.
2.
Establish all connections. In this connection, observe the operating instructions
of the system.
3.
Make sure that pipes and/or hoses are connected to all ports and/or that the
ports are closed with plug screws.
4.
Carry out a special check to make sure that the cap nuts and flanges are correctly
tightened at the pipe fittings and flanges.
Mark all checked fittings, e.g. using a permanent marker.
5.
Make sure that all pipes and hose lines and every combination of connection
pieces, couplings or connection points with hoses or pipes are checked for their
operational safety by a person with appropriate knowledge and experience.
6.
To avoid exceeding the maximum admissible operating pressure, the operating
pressure must be checked using a suitable measuring device during adjustments.
