3 Operation

3.1 Normal operation

Opening of closed valve

- without solenoid:

• before valve is opened ⎯ supply air pressure in closing direction

• air supply to connection «open»

• air release through connection «closed»

- with standard solenoid:

• supply specified control voltage to the coil

- with impulse solenoid:

• supply an impulse of specified control voltage to the coil for opening (pulse duration min. 50 ms)

- with radiation resistant solenoid:

• supply specified control voltage to the solenoid coil „open“ and coil „close“.

Closing of open valve

- without solenoid:

• before valve is closed ⎯ supply air pressure in opening direction

• air supply to connection «close»

• air release through connection «open»

- with standard solenoid:

• release control voltage

- with impulse solenoid:

• supply an impulse of specified control voltage to the coil for closing (pulse duration min. 50 ms)

- with radiation resistant solenoid:

• release control voltage from the solenoid coil „close“ and coil „open“.

3.2 Bakeout

extended compact

Valve: ≤ 300°C in open and closed position ≤ 200°C in open and closed position
Actuator: ≤ 200°C for max. 200h ≤ 200°C for max. 200h
Position indicator: ≤ 80°C (option: 200°C) ≤ 80°C (option: 200°C)
Solenoid ≤ 80°C ≤ 80°C
Heating and cooling rate: 50°C/h 50°C/h

Operate the valve only after the bake-out temperature has been stable for two hours. If actuation during bake-out is
required, the heating and cooling rate from 100°C to 200°C must not exceed 10°C/h.

Temperature differences exceeding 30°C throughout the valve are not allowed. They may affect the performance of
the valve.

3.3 Behavior in case of compressed air pressure drop

Valve closed: valve remains closed and leaktight
Valve open: valve position is undefined

3.4 Behavior in case of power failure

Standard solenoid: Valve closes
Solenoid for impulse actuation (option): Valve position does not change, a started movement will be completed.
Radiation resistant solenoid: Valve closes

3.5 Emergency operation at power failure (E4Gy)

Solenoids with an emergency operation (slotted screw) to operate the valve in case of a power failure (with com­pressed air available)

Standard solenoid
To close

the valve:

Turn the slotted screw counter-clockwise to its stop
To open

the valve:

Turn the slotted screw clockwise to its stop
For remote operation make sure that the slotted screw is turned

counter-clockwise to its stop.

Solenoid for impulse actuation
To close

the valve:
Turn the slotted screw (coil «closed») clockwise to its stop. If the valve
is closed, turn the screw back to its original position.

To open

the valve:
Turn the slotted screw (coil «open») clockwise to its stop. If the valve
is open, turn the screw back to its original position.

For remote operation make sure that both slotted screws are turned
counter-clockwise to their stop (original position).

Radiation resistant solenoid

In case of a power failure, the solenoid can be removed and compressed air can be connected directly to the
connection plate.

4 Trouble shooting

Failure Check Action

Power available? Check voltage!
Compressed air available? Check air pressure!

Valve mechanism does not move

Slotted screw in proper position? Check slotted screw!

When operating at atmosphere:
(not recommended)

No reason for concern Whistling sound during

opening/closing:

When operating at vacuum: No reason for concern unless the

sound gets extensive

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.
