6.2.3 Discharge conditions and reaction
forces
At low temperatures:
Outlet lines must be protected against
freezing. This applies in particular if gas
cooling as a result of expansion is to be
expected or lines are laid outdoors.
With crystallising media:
In the case of media which tend to
crystallise, solidify or stick, appropriate
action must be taken to ensure that the
solidification process cannot take place in
the inlet or outlet lines or in the body (e.g.
installed rupture disc, insulation, heating).
e.g. installed rupture disc, insulation,
heating
With gassing media
In the case of gassing or vaporising liquids,
adequately dimensioned flashtraps must be
located in the direct vicinity of the valve.
Reaction forces during discharge
The pipes and their holders are to be
dimensioned so that their weight forces and
the reaction forces and thermal loads
produced during discharge can be safely
absorbed.
Instructions for calculating the reaction forces are
contained in the Richter publication "Plan and install
safety valves".
6.3 Valve connecting dimensions
The main dimensions are contained in the
dimensional drawing in
Section 10.5 .
6.4 Flange caps and gaskets
♦ Contamination of or damage to the sealing
surfaces is best avoided if the protective caps
remain on the flanges until just before installation.
If plastic sealing surfaces, e.g. on mating flanges
made of metal or enamel, can be damaged, use
PTFE-lined seals with a metal inlay. These gaskets
are available as special accessories in the Richter
range.
6.5 Direction of flow and installa-
tion position
Qqq
The direction of flow must be observed
when installing the valve. It is indicated by a
direction arrow on the valve body.
♦ A mix-up of the inlet and outlet will result in the
valve becoming ineffective and the bellows may be
destroyed.
♦ Always install the safety valve with the stem in a
vertical position.

6.6 Grounding
The valve must be grounded. This can be achieved in
the simplest way via the pipe screws using tooth lock
washers. One pipe screw per flange is underlaid with
toothed disks.
At the customer's request a setscrew M6 with a hex.
nut and washer will be provided at each flange as an
additional grounding connection.
Otherwise grounding must be ensured by different
measures e.g. a cable link.
