If not indicated otherwise in the legends, the illustrations in this document cor-
respond to the valve with the nominal diameter DN 25 ISO-KF. They apply to
valves with other nominal diameters by analogy.
We reserve the right to make technical changes without prior notice.
The electromagnetically actuated bellows sealed angle valves are used as shut-off
or venting devices in vacuum applications.
The angle valves are opened electromagnetically and closed by means of a
prestressed pressure spring. They close, or remain closed, on power loss.

1 Description
The angle valve has two operating modes:
· REMOTE mode
Drive via control voltage 15 … 30 VDC.
· LOCAL mode
Drive via supply voltage 85 … 248 VAC.
The operating mode is selected by setting a switch (®212).
In the REMOTE mode, the supply voltage of 85 … 248 VAC is constantly fed. The
angle valve is opened and closed via the control contact (0 VDC).

4 Installation
Skilled personnel
The vacuum connection may only be established by persons who have
suitable technical training and the necessary experience or who have
been instructed by the end-user of the product.
DANGER
Caution: overpressure in the vacuum system >1 bar
Injury caused by released parts and harm caused by escaping process
gases can result if clamps are opened while the vacuum system is
pressurized.
Do not open any clamps while the vacuum system is pressurized. Use
the type clamps which are suited to overpressure.
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 one's bare hands increases
the desorption rate.
Always wear clean, lint-free gloves and use clean tools when working
in this area.
Keep the protective lids.
Remove the protective lids and install the valve to the vacuum system by means of
the small flange fittings.
Any installation angle and flow direction may be chosen.

Skilled personnel
The electrical connection, in accordance with the VDE 0100
guidelines, may be made only by a licensed electrician, qualified as per
VDE 0105. The line cables shall be isolated from the line supply during
all electrical work.
DANGER
Caution: mains voltage
Products that are not professionally connected to ground can be
hazardous in the event of a malfunction.
Connect the product according to the local regulations and ground it
correctly.
Caution
Caution: electrostatic fields
If the valve is installed in the vicinity of switched or electronically
controlled heavy electric loads, such as furnaces, heaters, motors or
RF generators, disturbances may occur.
Install a mains filter in the supply line of the valve.
Caution
Caution: high voltage tests
The valve is factory tested according to the DIN EN 60 204 standard.
Additional high voltage tests may destroy the valve.
Do not carry out any further high voltage tests.

DANGER
Caution: bursting pressure
Overpressures >3 bar (e.g. in the event of an explosion) can cause the
inside section and housing to burst. This could result in injuries caused
by catapulted parts and health damages due to leaking process gases.
Protect the entire vacuum system against overpressures >3 bar.
