Start-Up And Putting The Device Back Into Operation; Starting Up The Plant When Vapors And Liquids Are Controlled - Samson 2357-1 Mounting And Operating Instructions

Start-up
6.1 Start-up and putting the
device back into operation
1. Depending on the field of application,
allow the regulator to cool down or
warm up to reach ambient temperature
before start up.
2. Slowly open the shut-off valves in the
pipeline. Slowly opening these valves
prevents a sudden surge in pressure and
high flow velocities which can damage
the valve.
3. Check the regulator to ensure it functions
properly.
6.2 Starting up the plant when
vapors and liquids are
controlled
1. Open the shut-off valves slowly prefera-
bly starting from the upstream pressure
side. Open all shut-off valves upstream
of the tank.
2. Fill the plant slowly with the process me-
dium. Avoid pressure surges.
3. Make sure that the pressure rises simulta-
neously upstream and downstream of the
regulator to avoid damaging the plug.
4. To start up the regulator, open shut-off
valves slowly.
5. Check the adjusted pressure set point at
the pressure gauge installed near the
regulator.
