This manual applies to manuals with part number

PF B18 701 (EVL 063 P)

PF B28 701 (EVL 100 P)

PF B38 701 (EVL 160 P)

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.

rated cycle life (→24).

DANGER

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.

NOTE

Make sure to adhere to the special regulations concerning cleanliness and

damage prevention when working with vacuum components.
