Installation; Installing The Regulator - Samson 2479 Mounting And Operating Instructions

5.3 Installation

The components (valve, control thermostat
and, if applicable, thermowell) of the
SAMSON regulator are delivered separate-
ly. The activities listed below are necessary
for installation and before start-up of the
regulator.
NOTICE
!
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).
NOTICE
!
Risk of regulator damage due to the use of
unsuitable tools.
Î Only use tools approved by SAMSON
(see 'Tools' in Annex).
NOTICE
!
Risk of regulator damage due to the use of
unsuitable lubricants.
Î Only use lubricants approved by
SAMSON (see 'Lubricants' in Annex).

Installing the regulator

The regulator can be installed into the down-
stream pressure pipe (return flow pipe) or
the upstream pressure pipe (flow pipe) of the
plant. See installation examples in Fig. 5-2.
1. Close the shut-off valves (1, 8) upstream
and downstream of the regulator while
the regulator is being installed.
2. Remove the protective caps from the
valve ports of flanged valves before in-
stalling the valve.
3. Observe the flow direction through the
valve. The arrow on the valve indicates
the direction of flow.
4. Make sure that the correct gaskets are
used.
5. Bolt the pipe to the valve free of stress.
6. Mount the control thermostat.
− Fasten the control thermostat on the valve
by tightening the coupling nut (10). Ob-
serve the specified tightening torques
(see 'Tightening torques' in Annex).
7. Mount the control line. Observe the spec-
ified tightening torques (see 'Tightening
torques' in Annex).
8. Slowly open the shut-off valves in the
pipeline after the valve has been in-
stalled.
