The part number can be taken from the nameplate.
The functions described as well as the illustrations and data contained in this
manual are subject to change without notice.
The Angle valves described in this manual are used as shut off valves in vacuum
systems and vacuum pumping stations.
The Angle valves are opened by a compressed air piston and closed by at least
one pressure spring. They close automatically in the event of a power or com-
pressed air failure.
The Angle valves have a floating switchover contact for both final positions.

DANGER
The valve may only be connected to the electric power supply if:
• if the angle valve is installed in a vacuum system
• the moving parts (valve plate etc.) are protected against accidental
contact.
The controller must be turned off before the valve is connected or dis-
connected.
The mains connector may only be plugged into a socket with a protective
ground. The protection must not be nullified by an extension cable without
ground conductor.

Neither the operator nor third parties shall perform maintenance work not
described in this manual.
DANGER
Persons performing maintenance work must first receive information concerning
the state of the contaminated vacuum units and their components.
Before installing or removing the product and for all maintenance work, the elec -
tric power and the compressed air supply have to be interrupted.
The connection to the compressed air and to the electric power may only be
established if:
• the angle valve is installed in a vacuum system or
• the moving parts (valve plate etc.) are protected against accidental contact
Please note that loaded springs and air cushions in the cylinder represent
potential hazards even when the supply lines are disconnected.
When using cleaning agents make sure to adhere to the applicable handling and
disposal regulations and safety measures.
