5.3 Installation
Tested SAMSON regulators are delivered as
an assembled unit. In all other cases, the
separate components (valve, actuator and
control line) of the regulator are delivered
separately. Upon delivery, the separate com-
ponents must be assembled together. The ac-
tivities listed below are necessary for instal-
lation and before start-up of the regulator.
Risk of regulator damage due to exces-
sively high or low tightening torques.
Observe the specified torques when tighten
-
ing regulator components. Excessive tighten
-
ing torques lead to parts wearing out more
quickly. Parts that are too loose may cause
leakage.
Î
Observe the specified tightening torques
(see 'Tightening torques' in Annex).
Risk of regulator damage due to the use of
unsuitable tools.
Î
Only use tools approved by SAMSON
(see 'Tools' in Annex).
Risk of regulator damage due to the use of
unsuitable lubricants.
Î
Only use lubricants approved by
SAMSON (see 'Lubricants' in Annex).

5.3.1 Installing the regulator
1. Close the shut-off valves upstream and
downstream of the regulator while the
regulator is being installed.
2. Remove the protective caps from the
valve ports before installing the valve.
3. Lift the valve using suitable lifting equip-
ment to the site of installation. Observe
the flow direction through the valve. The
arrow on the valve indicates the direction
of flow.
4.
Make sure that the correct flange gaskets
are used.
5.
Bolt the pipe to the valve free of stress.
6. Mount the actuator.
Î
Diaphragm actuator DN 15 to 100
−
Push the actuator stem (11) through the
hole in the crossbeam (8) onto the spig-
ots of the bellows (5.1).
−
Align actuator stem (11) and fasten with
the nuts (9). Observe the specified tight
-
ening torques (see 'Tightening torques' in
Annex).
Î
Bellows actuator DN 15 to 50
−
Remove the crossbeam (8) from the
valve.
−
Push the actuator with actuator stem (11)
onto the spigots of the bellows (5.1).
−
Align pillars (8.1) and fasten the actua-
tor with the nuts (8.2). Observe the spec-
ified tightening torques (see 'Tightening
torques' in Annex).
