4 Assembly and Operation
4.1 Assembly Instructions
• Make certain the
fi
tting is suitable for the relevant ap-
plication. The
fi
tting must be suitable for the operating
conditions of the pipeline system (medium, concentra-
tion, temperature and pressure) as well as the relevant
ambient conditions.
• Check the
fi
tting for transport damage before installing
it. If the
fi
tting is damaged do not install it.
• The planner, the construction company or operating
company are responsible for the positioning and instal-
lation of the
fi
tting. Planning and installation errors can
adversely affect the reliable functionality of the
fi
tting
and may represent a signi
fi
cant potential for hazard.
• After the
fi
tting is installed perform a tightness and
function check.
4.2 Tools Required
The tools required for installation and assembly are not
included with delivery.
4.3 Connect the Pressure Keeping Valve
• The
fi
tting must be connected to the pipeline so it is
free of mechanical stress.
• The pressure keeping valve has a female thread (ISO,
DIN, ANSI) and can be connected with various connecting
elements of the
em
technik system.
Cylindrical thread
Conical thread
Sealing is provided by a sealing collar for
Cylindrical threads (G, M or UNF).
A version with an O-ring is also possible.
Sealing is provided
by the thread itself
for Conical threads
(NPT).
Sealing Collar
O-Ring
Thread
• Each thread must always be connected with the same
thread type.
• If a plastic
fi
tting is used in combination with a metal-
lic male
fi
tting, additional sealing with Te
fl
on® tape is
recommended.
4.4 Operation / Set Opening Pressure
1. Pull off the cover cap (pos. 1) on the top of the
fi
tting
