Starting Up The Plant; Regulation Of Liquids; Regulation Of Steam - Samson 2417 Series Mounting And Operating Instructions

6.2 Starting up the plant

Î Start up the regulator after mounting all
parts. Make sure the control line is open
and correctly connected.
Î Open the shut-off valves slowly prefera-
bly starting from the upstream pressure
side. Afterwards, open all the valves on
the consumer side (downstream of the
regulator).
Î Fill the plant slowly with the process me-
dium. Avoid pressure surges.
Î Make sure that the pressure rises simulta-
neously upstream and downstream of the
regulator to avoid damaging the balanc-
ing bellows.

Regulation of liquids

To start up the excess pressure valve, open
shut-off valves slowly.
Î For medium temperatures above 150 °C,
first fill the compensation chamber with
the process medium.

Regulation of steam

Unscrew filler plug (19) on the compensation
chamber (18). Use the included plastic fun-
nel or a jug to pour in water until it starts to
overflow. Screw the filler plug back in and
tighten it.
Î All pipes conveying the process medium
must be completely drained and dry.
Î Air and condensate must be allowed to
escape from the plant.
Î Allow time for the pipes and valves to
heat up.
