1 Use of product
Use product for clean and dry indoor vacuum applications under the conditions indicated in chapter «Technical data» only!
Other applications are only allowed with the written permission of VAT.
1.1 Technical data see product data sheet
(product data sheet on request)
2 Installation
Do not lift the valve at the actuator! The valve may get damaged
2.1 Unpacking
Make sure, that the delivered components are according the order.
Visually check the quality of the components.
If something of the delivery is not as expected please immediately contact VAT.
Notice:
Please do not throw away the original packaging. Packaging my useful in a case of service to return the components to
VAT.
2.2 Installation into the system
The valve seat side is indicated by the symbol " " on the connection flange.
2.3 Tightening torque for flange screws
2.3.1 Mounting with centering ring
Tighten mounting screws of the flanges uniformly in crosswise order. Observe the maximum torque levels in the following
table. Higher tightening torques deform the valve body and can lead to an improper function of the valve. ATTENTION: Do
not install the flange screws over the maximum specified depth. A flange screw which is installed over the maximum depth
may result in a damage of the valve!

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.
