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 w it h the written permission of VAT.

1.1 Technical data

Pressure range 1 x 10

-10

mbar to 1.6 bar (abs)
Differential pressure on the gate ≤ 1.6 bar in either direction
Differential pressure at opening ≤ 30 mbar
Admissible temperature: Valve ≤ 250°C open, 200°C closed

Pneumatic actuator ≤ 200°C
Position indicator ≤ 80°C
Solenoid ≤ 50°C

Position indicator: contact rating 5 A / 250 V AC, 3 A / 50 V DC
Solenoid see tag on solenoid

2 Installation

2.1 Installation into the system
Admissible forces

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 valv e. The stress has to be relieved by suitable means, e.g. bell ows sections. The
following forces are admissible:

DN (nom. I.D.) Axial tensile or

compressive force «FA»

Bending moment «M»

mm inch N lbf Nm

lbf • ft

63 2½ 2000 448 80 59
100 4 2500 560 100 74
160 6 3000 672 150 110
200 8 3000 672 150 110

If a combination of both forces («FA» and «M») occurs, the values mentioned
above are invalid. Please contact VAT for more information.

2.2 Connections

2.2.1 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 thr ead R

/8 "

Remove 2 vent plugs from «A» and «B»
Compressed air to connection <A>:

Valve opens
Compressed air to connection <B>:

Valve closes
Compressed air pressure (min. - max . overpressure): 4 - 7 bar / 55 - 100 psig

Use only clean, dry or slightly oiled air!

2.2.2 Electrical connection

Do not touch electrical parts under vo lt age!

Connect electrical power only if

- valve has been installed into the vacuum system

- moving parts cannot be touched
Verify that mains voltage matches voltage stated on the solenoid! Sockets for position indicator and

solenoid are supplied with the valv e.
Wire solenoid and position indicator according to the following diagrams:

Emergenc y operat i o n at power fai l u r e

In case of a power failure, the valve can be actuated man uall y if compressed air is available.

Standard solenoid Solenoid for impulse actuation (option)

Press push-button: valve opens
Release push-button: valve closes

Press push- button: valve opens

Pull push-button: valve closes

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!

Global leak at bonnet seal after heatin g the valve!

Due to a possible settlement of screw and VATS EAL 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 11 item 61)
and tighten the screws if necessary with a torque wrench.

Remark:
Do tight screws crosswis e!
Necessary torque of screws is for
DN63, DN100 and DN 160; 20 Nm /15 lbf . ft.
DN200; 40 Nm / 30 lbf . ft.

5 Maintenance & r epairs

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 S w it z e r land
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.

Keep fingers and objects away from the v alve 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.
