INSTALLATION AND MAINTENANCE
AS-SUPPLIED CONDITION
The shut-off valve and the soft-start device are supplied as a compact assembly.
The shut-off and solenoid/air controlled soft-start valve assembly is designed to receive 3/2 NC solenoid valves with a size 15
or 30 CNOMO mating surface (solenoid valves 302, 189, 190 or 192 supplied separately).
Manual override on solenoid valves: The assembly can only be piloted with solenoid valves without manual override or
with a non-locking manual override (impulse-type).
INSTALLATION
The shut-off and soft-start valve assembly must be mounted first in the pneumatic system, after the filter, filter/regulator or
filter + regulator and before any lubricator. The standard assembly kit (see below) enables direct connection of the assembly
to a FRL system of the MODULAIR type 107 or 112.

The components are designed for left-to-right flow (as indicated by the symbols). The air flow
direction is indicated on the front by an arrow. If you wish to obtain reversed mounting order
with air circulation from right to left: please consult us.
MOUNTING AND OPERATING INSTRUCTIONS
!
- The shut-off and soft-start valve assembly must be mounted as described above before the lubricator.
Make sure there is no oil.
- Do not obstruct exhaust port 3 on the shut-off valve.
- Make sure that port 3 cannot be obstructed inadvertently.
- In case of operation in dusty environments, mount an exhaust silencer on port 3 (available as
accessory).
- Make sure to meet the operating specifications (pressure, temperature, voltage, current) of the
assembly as described opposite.
- The solenoid valves must not be equipped with locking manual override.
- The shut-off valve must only be de-energised in case of need when the system is generally
shut down or in case of power supply failure. This product is not a limit stop switch.
- For systems which are operated only infrequently (e.g. in case of continuously operated machines),
the correct functioning of the shut-off and soft start valve assembly must be regularly checked
- at least once per month – by turning the power on and off several times (full exhaust and gradual
pressurisation of the system).
- Should a failure occur, please return the product to your distributor with a description of the operating
conditions and the problem.

NOTE - The centre distances for mounting the main combinations of this assembly with other components or
accessories of the Modulair 107 or 112 range are given in a table: see MS-P710-4.
- A silencer (accessory) can be fitted underneath the shut-off valve, see above.
MOUNTING OF SHUT-OFF AND SOFT-START VALVE ASSEMBLIES ORDERED SEPARATELY
It is possible to combine components ordered separately using the assembly kit and side mounting brackets for installation
(fastenings to be ordered separately).
However, a unit consisting of separately ordered components is longer (Modulair 112) than the compact unit shown above.
