Tighten mounting screws of the flanges uniformly in crosswise order.
Observe the maximum torque according to the grade of screws and depth of
thread you use.
Admissible forces
Forces from evacuating the system, from the weight of other components, and from heating can lead to deformation of the
valve body and to malfunction of the valve. The stress has to be relieved by suitable means, e.g. bellows sections. The
following forces are admissible:

Preventive maintenance
The numbers in brackets refer to the drawing on page 9
Note! The process environment of your application (i.e. corrosive gases, deposition on parts inside valve body) may
require more frequent preventive maintenance intervals than suggested below.
Heating of the valve is highly recommended for contaminating processes. VAT offers customized heater
boxes for series 64.2 valves.
For quick maintenance, VAT recommends to exchange the complete gate assembly in order to reduce
downtime of the system.
Warning! Never remove striking plate (20) from the mechanism (16)!
Recommended maintenance after every 100'000 cycles (25’000 for DN 400 vertical mounting only):
- Clean gate O-ring, clean inside surfaces
- Inspect the bonnet seal, ball bearings and crank bolt.
- Replace items (Spare part kit ‘C’), if corrosion or deposition of process by-products occured.
- In corrosive processes: Relubricate locking balls with VAT Vacuum grease. Replace and lubricate locking balls, if
corrosion has occured.
Recommended maintenance after every 200'000 (50’000 for DN 400 vertical mounting only) cycles:
In additional to the 100'000 cycles maintenance interval, VAT recommends to clean and lubricate the ball bearings
(replace, if necessary), replace the locking balls, replace the crank bolt, inspect, clean and re-lubricate the ball guide plate
(replace, if friction increased), inspect, clean and re-lubricate the feedthrough O-ring (replace it if necessary)
The following table refers to the items on page 4 and the spare parts list on page 6.

Repairs
Contact VAT for repairs or maintenance. The fabrication No. marked on the valve body has always to be specified. It has
to be individually decided whether the work can be performed by the customer or has to be carried out by VAT.
Power to the control unit has to be switched off and the cable to the valve has to be disconnected (wait at least 60
seconds) before removal/installation of the valve from/into the system.
Keep fingers and objects away from the valve opening!
Products returned to VAT for repair have to be free of harmful substances such as e.g. toxical, caustic or microbiological
ones. For radioactively contaminated products the customer has to fill in the VAT form «Contamination and Radiation
Report» and to send it with the product. The form is available at VAT. The maximum permissible values indicated in the
form must not be exceeded.
Warranty
Each product sold by VAT Vakuumventile AG (VAT) is warranted to be free from the manufacturing defects that adversely
affect the normal functioning thereof during the one-year period immediately following delivery thereof by VAT, provided
that the same is properly operated under conditions of normal use and that regular, periodic maintenance and service is
performed or replacements made, in accordance with the instructions provided by VAT. The foregoing warranty shall not
apply to any product or component that has been repaired or altered by anyone other than an authorized VAT
