NOTICE
Damage of the valve
The valve may be damaged through in-
appropriate installation.
→
Only trained and authorized specialists
may install the valve.
→
Only use appropriate tools and suitable
sealing materials.
→
Make sure that the valve is mounted in
flow direction.
→
Make sure not to distort the valve body,
particularly in case of a misaligned pipe-
work.
There must be no mechanical loads ap-
plied to the solenoid.
→
Do not use solenoid as a lever during
mounting.
Valve only firmly closes in flow direction.
Inflow against the valve’s flow direction
may lead to the destruction of compo-
nents.
→
Implement adequate measures if back flow
is to expect. Examples:
→
By providing a safety shutdown and a relief
of the compressed air systems on the
valve’s inlet side.
→
By adding check valves to the pipe sys-
tem.
The valve subassembly may get damaged
by external loads at the operating site.
→
Protect valve from objects falling down.
→
Protect valve from direct weather influen-
ces.

Conditions of installation
Compliance with operating limits
Ensure to comply with the operating limits pri-
or to mounting the valve. Observe the valve’s
data sheet.
Planning of the pipe system
Buschjost recommends to include manual stop
valves and drain valves in the plant so that the
pipe system may be depressurized and drained
prior to working on the valve.
Mounting position of the valve
The mounting position is not determined.
preferably: solenoid vertical on top

Preparation
→
Check the valve for externally visible
damages.
→
Leave the valve in its protective package
prior to mounting.
→
Make sure that there is enough free space
for dismantling the valve in case of main-
tenance.
→
Clean the pipe system prior to mounting the
valve.
7.3
Mount valve to pipe line
→
Mount the valve to the designated pipeline.
Comply with existing connections.
→
Arrange the valve according to the
pipeline’s flow direction. An arrow on the
valve’s body marks the flow direction.
