4.1 Unpacking
Handling of the valve must take place under clean conditions normally observed in good
vacuum practice. The valve may only be touched with clean gloves. After the protective
covers have been removed, the sealing surfaces of the flanges have to be cleaned carefully
with alcohol. The screws of the flanges have to be tightened uniformly in diagonal crosswise
order. Determine that the valve and existing plumbing in the vacuum system will be
adequately supported.
•Make sure that the supplied products are in accordance with your order.
•Inspect the quality of the supplied products visually. If it does not meet
your requirements, please contact VAT immediately.
•Store the original packaging material. It may be useful if products must be
returned to VAT.
Keep valve in the plastic bag until it is being installed into the system.
NOTICE
Sensitive product
Valve parts may get damaged.
–
When lifting the valve, pay attention that the valve does not touch any solid
objects.
– Lift valve carefully and put it down on a clean surface or
mount it to a clean
system.

WARNING
Unqualified personnel
Inappropriate handling may cause serious injury or property damage.
Only qualified personnel are allowed to carry out the described work.
NOTICE
Inappropriate mounting position of valve
Maintenance may be troublesome and parts may drop down.
Ideally dismount valve from the system and put it on a clean workbench with
the actuator upwards.
7.1 Maintenance intervals
Under clean operating conditions the valve does not require any maintenance during
specified lifetime.
•Impacts from the process may require more frequent maintenance.
•When the valve has reached the specified lifetime; see product data sheet,
we recommend to have it serviced by VAT. Please contact your nearest
VAT service center to get recommendations and an offer. You will find the
addresses on our website www.vatvalve.com.
7.2 Preventive Maintenance
If there is a small leak please try to clean the sealing surface and the seal ring with a lint
free towel and some alcohol.
If this doesn’t help you can increase the sealing force by increasing the closing torque. The
maximum torque is specified in the table under normal operation.
It’s not allowed to exceed the maximum specified torque.
