2.3 Connections
2.3.1 Compressed air connection
Connect compressed air only when
- valve is installed into the system
- moving parts cannot be touched
The valve is opened by a spring at compressed air failure.
Connection: Internal thread M5 (adapter as option)
Compressed air pressure (min. - max. overpressure): 4 - 8 bar / 60 - 115 psi
Use clean, dry or slightly oiled air only!

5 Maintenance & repairs
Under clean operating conditions, the valve does not require any maintenance during the specified cycle life.
Contamination from the process may influence the function and requires more frequent maintenance.
Before carrying out any maintenance or repairs, please contact VAT. It has to be individually decided whether the
maintenance/repair can be performed by the customer or has to be carried out by VAT. The fabrication number on the
valve
made in Switzerland
Fabrication No.:
patented
. .
. . . . . – . . . . – . . . . / . . . .
A – . . . . . .
Fabrication number
has always to be specified.
All supplies (e. g. compressed air, electrical power) must be disconnected for removal/installation of the valve from/into the
system and for maintenance work.
Even with disconnected supply, loaded springs and/or air cushions in cylinders can be potential hazards.
Keep fingers and objects away from the valve opening!
Products returned to VAT must be free of harmful substances such as e.g. toxical, caustic or microbiological ones. If
products are radioactively contaminated, fill in the VAT form «Contamination and Radiation Report» and send it with the
product. The form is available at VAT. The maximum values indicated in the form must not be exceeded.
