Danger – endangerment caused by product-specific and process-specific
conditions!
Disassembling the valve from the piping
system without relieving the system
pressure first may result in burns,
scalding or chemical burns.
If the valve in a system is operated with
acidic or alkaline media, your hands and
fingers may suffer chemical burns when
disassembling the valve.
If the valve in a piping system is
operated with hot media, the surface
temperature of the valve can also reach
this value.
Never place your hand inside the valve
housing when the compressed air
supply is connected.
The valve weighs several kilograms.
The valve contains pretensioned
pressure springs. Personal injuries
may occur during installation.

The valve may not work any longer or
malfunction considerably if faulty or non-
specified parts are installed on the valve.

The valve’s function can be disturbed greatly
by different operating conditions.
Make sure of proper utilisation.
