2 Safety
2.1 Intended use
The v alv e is intended for installation in a pipeline or pressure tank sy stem in order to block media or allow
them to pass through within the permissible operating conditions. The permissible operating conditions
are specif ied in these operating instructions.
The v alv e is suitable for the media listed in these operating instructions; see section 4.5 “Media”.
Operating conditions and applications dev iating from these require the approval of the manufacturer.
Only media may be employed to which the materials used for the valve body and seals are resistant.
Contaminated media or usage outside of the pressure and temperature specifications can lead to damage
to the v alv e body and seals.
Avoidance of foreseeable incorrect use
Nev er exceed the permissible usage limits specified in the data sheet or in the documentation
with regard to pressure, temperature, etc.
Follow all saf ety instructions and operating procedures in these operating instructions.
2.2 Meaning of the operating instructions
The operating instructions are to be read and f ollowed by the responsible technical personnel before
mounting and start-up. As part of the valve the operating instructions must always be available close to it.
People could be seriously injured or killed if the operating instructions are not followed.
Read and observ e the operating instructions before using the valve.
Retain the operating instructions and make sure they are available.
Pass on the operating instructions to subsequent users.

4.3 Intended use
Div erter plug v alve for the installation of two safety valves in combination with bursting discs for protecting
gas storage tanks. The requirements of the pressure equipment directive for redundant or different types
of saf ety devices are f ulfilled with this valve and in combination with safety valves with the same setting
pressure. Additional connections for suitable bursting discs are av ailable on each side.
In the case of serv icing the safety valves or replacement of the bursting discs, the side to be serviced is
isolated f rom the tank.
In the end position one outlet is open and the other is closed. It is not possible to shut off both outlets at
the same time.

Only install the v alve if the maximum operating pressure and operating conditions correspond to
the marking on the v alv e.
Remov e protective caps or covers before mounting.
Inspect the v alve for dirt and damage. DO NOT install a damaged or dirty valve.
Remov e any dirt and residues from the pipeline and v alve in order to prev ent leaks.
Av oid damaging the connections.
The sealing surf aces must remain clean and intact.
Seal the v alv e with suitable seals.
No sealant (sealing tape, liquid sealing tape) may enter the v alve.
Respect the suitability for use with O2.
Connect pipelines in a f orce-f ree and torque-free manner.
Stress-f ree mounting.
In order to ensure trouble-f ree operation, no impermissible static, thermal or dynamic stresses
may be transmitted to the valve. Observe reaction forces.
Temperature-dependent changes in length in the pipework sy stem must be compensated with
expansion joints.
Fasten the v alve in the body with the existing threads.
