Installation
Caution
Caution: vacuum component
Dirt and damages impair the function of the
vacuum component.
When handling vacuum components, take
appropriate measures to ensure cleanliness and
prevent damages.
Caution
Caution: dirt sensitive area
Touching the product or parts thereof with bare
hands increases the desorption rate.
Always wear clean, lint-free gloves and use
clean tools when working in this area.
•The valve is delivered in closed condition and with the
rotary knob installed.
•The protective packaging should not be removed until
shortly before installation. Even the slightest contami-
nation could cause leaks.
Installation
Space requirements
Make sure the valve can be operated without any risk of
bodily injury.

Start-Up
Bakeout
It is good practice to bake out new valves and valves the
inner parts of which have been exposed to atmosphere for
some time, e.g. with a heating sleeve.
DANGER
DANGER: hot surface
Touching the hot surface (>55 °C) can cause
burns.
Do not touch the hot surface
Caution
Caution: bakeout at atmosphere
Baking out with the inner parts of the valve ex-
posed to atmosphere may lead to the formation
of oxides and thus cause leaks.
Bake out the valve only if
•the pressure in the vacuum system is
<1×10-4 mbar or
•the vacuum system has been vented with
inert gas.
nPrior to baking the valve at temperatures >80 °C,
remove the rotary knob (→section "Operation",
"Installing/Removing the Rotary Knob").
oBake the valve out.

pIf the rotary knob has been removed, wait until the
valve has cooled down (<50 °C) and reinstall the rotary
knob (→section "Operation", "Installing/Removing the
Rotary Knob").
Bringing the Valve Plate Into the Defined
Position
Close the valve by turning the rotary knob until the stop
position is reached.
The valve is closed and ready for use now.
Operation
Prevent the entry of dirt, dust, or other abrasive contamina-
tion into the valve. Even very small particles on the sealing
surfaces may cause leaks.
°C
DANGER
DANGER: hot surface
Touching the hot surface (>55 °C) can cause
burns.
Wear protective gloves.
Caution
Caution: bakeout at atmosphere
Baking out with the inner parts of the valve ex-
posed to atmosphere may lead to the formation
of oxides and thus cause leaks.
Bake out the valve only if
•the pressure in the vacuum system is
<1×10-4 mbar or
•the vacuum system has been vented with
inert gas.
Closing the Angle Valve
Depending on the operating temperature, close the valve
with the rotary knob or a ring wrench.
Procedure
Operating temperature ≤55 °C
Close the valve by turning the rotary knob clockwise until the
stop position is reached.
Operating temperature >55 °C
Precondition: rotary knob removed.
Close the valve by turning the ring wrench clockwise until the
stop position is reached. Remove the ring wrench.
°C
Use the ring wrench
only temporarily
Caution
Caution: excessive closing force
Only little force is required to close the valve. If
the hex head is turned beyond the stop position,
the sealing surfaces and/or the spindle may get
damaged.
Do not turn the hex head beyond the mechanical
stop.
Opening the Angle Valve
Depending on the operating temperature, close the valve
with the rotary knob or a ring wrench.
The maximum opening of the valve is limited by a mechani-
cal stop.
Procedure
Operating temperature ≤55 °C
Open the angle valve by turning the rotary knob counter-
clockwise.
Operating temperature >55 °C
Precondition: rotary knob removed.
Open the valve by turning the ring wrench counter-clockwise.
Remove the ring wrench.
°C
Use the ring wrench
only temporarily
Installing/Removing the Rotary Knob
Using a screwdriver (size 4 mm), loosen/fasten the screw.

Deinstallation
DANGER
DANGER: contaminated parts
Contaminated parts can be detrimental to health
and environment.
Before beginning to work, find out whether any
parts are contaminated. Adhere to the relevant
regulations and take the necessary precautions
when handling contaminated parts.
Caution
Caution: vacuum component
Dirt and damages impair the function of the
vacuum component.
When handling vacuum components, take
appropriate measures to ensure cleanliness and
prevent damages.
Vent the vacuum system and wait until the valve has
cooled down to <50 °C.
Detach the flanges and put the protective lids in place.

Storage
Caution
Caution: vacuum component
Inappropriate storage leads to an increase of the
desorption rate and/or may result in mechanical
damage of the product.
•Cover the vacuum ports of the product with
protective lids or grease free aluminum foil.
•Close the valve up to the stop position (which
ensures optimum storage).
•Do not exceed the admissible storage
temperature range (→Technical Data).
