3 Operation
3.1 Normal operation
Valve with pneumatic actuator: - valve is closed by a spring (NC)
- valve is opened pneumatically
3.2 Operation under increased temperature
See «1.1 Technical data»
3.3 Behavior in case of compressed air pressure failure
Valve closed: valve remains closed and leaktight
Valve open: valve closes leaktight
3.4 Behavior in case of power failure
Valve with solenoid valve:
Valve is closed leak tight by a spring
Valve without solenoid valve:
Depending on the installation of the customer
4 Trouble shooting
Failure Check Action
Valve does not open Power available? Connect correct voltage
Compressed air available? Connect correct air pressure

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.
