2 Installation
2.1 Unpacking
As this valve is a heavy component you should lift it with adequate equipment to prevent any injury to
humans.
DN200 (8”) and DN250 (10”) valves are equipped with attachment points (tapped holes). Add eyebolts
to these attachment points for lifting. The attachment points are indicated on the dimensional drawing of
the specific valve part number (available on request).
Never lay the valve down with actuator downwards as the actuator may be damaged.
2.2 Installation procedure
Fingers and objects must be kept out of the valve opening and away from moving parts.
The valve plate may start to move just after power is supplied.
Do not connect or disconnect sensor cable when device is under power.
Do not disconnect air supply when device is under power.
2.2.1 Install valve into system
• Valve seat side should face process chamber. The valve seat side is indicated by the symbol "∇" on the valve
flange.
• The valve is a heavy component you should lift it with adequate equipment for installation into system
Note:
• Make sure that enough space is kept free to do preventive maintenance work. The required space is indicated on
the dimensional drawing.
• Make sure that the valve is not hanging at screws while installation
• If you use a body flange compl. (S650_DN200, ISO-F) see figure below
Note:
• Screw in all screws and tighten by hand
• Fasten all screws by numbers from 1 to12 uniformly
step by step, and according with tables on page 5 & 6
(max. tighening torque Nm).

Do not tighten flange screws stronger than indicated in the tables below. The max. tightening torque
depends on the type of installation.
Note: Tighten mounting screws of the flanges uniformly in crosswise order. Observe the maximum torque levels in
the following tables (a, b + c). Higher tightening torques deforms the valve body and may lead to malfunction of the

are capable to withstand applied torques. Also use slightly lubricated screws and make sure that screws are not too long
otherwise the valve body may be damaged.
Do not admit higher forces to the valve than indicated in the table below.
c) Admissible forces
Forces from evacuating the system, from the weight of other components, and from baking can lead to deformation and
malfunctioning of the valve. Stress has to be relieved by suitable means, e.g. bellows sections.

4 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

Fabrication No.: patented . .
. . . . . – . . . . – . . . . / . . . .

– . . . . . .
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.

4.1 Preventive maintenance procedures
Keep fingers out of the valve body during preventive maintenance work. The sealing ring or its retaining
pins will lower in case of electrical power failure or loss of compressed air.
Take precautions to protect yourself from harmful substances that may have contaminated the valve
during use.
Two preventive maintenance procedures are defined for this valve. These are:
• Replacement of isolation seals (gate and body seal of sealing ring) and valve cleaning
• Replacement of actuator shaft seals
Required frequency of cleaning and replacement of seals is depending on process conditions.
A critical factor influencing the maintenance period is the lifetime of the vacuum grease, being limited under
increased temperature. In this case grease will separate to PTFE and oil. The oil may flow and contaminate
the valve parts.
VAT can give the following recommendations for preventive maintenance:
unheated *) heated ≤ 80°C *) heated > 80°C *)
isolation seals (gate and body seal of sealing ring) 200’000 cycles 6 months 3 months
actuator shaft seals 1 Mio. cycles 6 months 3 months
*) These figures are reference values for clean conditions under various temperatures. These values do not include any
impact of the process. Therefore preventive maintenance schedule has finally to be checked for the actual process
conditions.
Prevent gap between body and sealing
ring from air gun cleaning. Otherwise
vacuum grease may be distributed and
contaminate the valve.
