DESCRIPTION
- Gradual pressurization after an outage leading to
venting of the system.

ADJUSTMENT OF DOWNSTREAM
PRESSURE BUILD-UP TIME (See page 15)
In both soft-start device versions, the filling rate, i.e. the
pressure build-up in the downstream circuit, is adjusted by
means of a fine-thread screw. Components are supplied
with 7 l/min screw adjustment.

The 3/2 NC shut-off valve, controlled by a solenoid valve
of the CNOMO pad-mounting type, vents the system

Upon pressurization, when the soft-start device is
in its initial position, an adjustable air flow ensures
