Adjustment to give steam-tight shut-off
To prevent steam loss you can adjust the
equipment to give steam-tight shut-off. To do so
you have to set the minimum flowrate to zero.
Attention!
Malfunctions due to banking-up of
condensate.
Limiting the maximum flowrate changes
the factory-set leak passage ("partial
flow"). The equipment closes as soon as
steam arrives. Note that the
responsiveness of the membrane regulator
is reduced due to the lack of a partial flow.
As a result condensate may bank up.

Make sure that the process in the
higher-level plant system is not
impaired by banking-up of
condensate.
To ensure that the equipment gives steam-tight
shut-off the following work must be performed on
the lower adjustment screw:

Make sure that the equipment is depressurized,
cooled down to room temperature and free from
fluid.

To reduce the pressure through the bore in the
cover slowly loosen the sealing plug by two
turns (10).

Remove the cap nut (1).

Remove the outer gasket (26) from the
adjustment screw.

Remove the hexagon nut (25).
 Remove the inner gasket (26) from the
adjustment screw.
 Screw out the adjustment screw (12) until a
resistance is felt.
