2.3 Admissible forces
Tighten mounting screws of the flanges uniformly in crosswise order. Observe the maximum torque of
9 Nm / 6.5 lbf .ft for CF flanges
Forces from evacuating the system, from the weight of other components, and
from baking 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:
Axial tensile or compressive force «FA»: 500 N / 112 lbf
Bending moment «M»: 30 Nm / 22 lbf .ft
If a combination of both forces («FA» and «M») occurs, the values mentioned
above are invalid. Please contact VAT for more information.
2.4 Connections
2.4.1 Compressed air connection
Connect compressed air only if
- valve has been installed into the vacuum system
- moving parts cannot be touched
With solenoid: Connect compressed air to IN (internal thread R 1/8“, 1/8“ NPT for USA)
Without solenoid: Connect compressed air to OPEN and CLOSE (internal thread M5)
Compressed air pressure (min. - max. overpressure): 5.0 - 7 bar / 72.5 - 100 psig
Use only clean, dry or slightly oiled air!

4 Trouble shooting
Valve does not close/open: Power available?
Compressed air available?
Solenoid defective?
Check voltage!
Check air pressure!
Leak at gate: Clean valve seat and gate!
Replace gate if damaged!
Correct air pressure?
Leak at body: Flanges leaktight?
Replace bonnet seal!
4.1 Global leak at bonnet seal after heating the valve!
Due to a possible settlement of screw and VATSEAL it could happen that after a heat up and cool down procedure the
bonnet seal becomes slight leaky. In this case please check the torque (see below) of bonnet screw (see page 13 item 15)
and tighten the screws if necessary with a torque wrench.
Remark:
Do tighten screws crosswise!
Necessary torque of screws is for DN16 -DN50; 10 Nm / 7.4 lbf .ft.
If you need any further information, please contact one of our service centers. You can find the addresses on our website:
http://www.vat.ch
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

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.
5.1 Replacement of actuator/gate assembly
The figures in brackets refer to the drawing on page 13
1. Vent vacuum chambers on either side of valve
2. Open valve
3. Disconnect compressed air
4. Disconnect electrical power
5. Disconnect compressed air line and plug (4) from solenoid and plug (2) from position indicator
6. Remove screws (15) from bonnet
7. Withdraw actuator/gate assembly carefully from body and put it on a clean place
8. Check and clean sealing surfaces of bonnet and valve seat
9. Put new bonnet seal «VATSEAL» (7) on body or bonnet (depending on mounting position)
Attention: Bordering of 2 bore holes must be on the body side!
10. Insert actuator/gate assembly carefully. At first, insert two screws (15) at both centering holes (bordering) of the bonnet
seal « VATSEAL» (7) and tighten them slightly only. Afterwards, tighten all screws (15) uniformly in crosswise order
(diagonal), in 2 or 3 steps, by means of the supplied hexagon pin spanner.
Notice! A suitable torque wrench with the appropriate hexagonal insert to tighten the screws
(tightening torque: 10 Nm) is available from VAT (item 10, 11, 12)
11. Connect plug (2) to position indicator
12. Connect plug (4) to solenoid

5.3 Replacement of position indicator
Fig 1
Before mounting the new position indicator, move the gate to the
intermediate position. Then attach new position indicator.
Gate valve with double acting pneumatic actuator:
Move gate to the intermediate position by compressed air.
Gate valve with single acting pneumatic cylinder and closing spring:
Move gate to the intermediate position by compressed air and keep up
an air pressure of approx. 2.5 bar ( 35 psig) in order to maintain the
intermediate position.
Fig 2
Correct mounting of position indicator, i.e. valve piston is not blocked by
the position indicator actuator.
(see circle marking)
Fig 3
Wrong mounting of position indicator, i.e. valve piston is blocked by the
position indicator actuator (see circle marking).
In this case, valve cannot be opened.
