conditions are specified in these operating instructions.
The diverter valve is suitable for the media listed in these operating instructions; see section 4.5 "Media".
Operating conditions and applications deviating 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 valve body and seals.
Avoidance of foreseeable incorrect use
Follow all safety instructions and operating procedures in these operating instructions.
2.2 Meaning of the operating instructions
The operating instructions are to be read and followed by the responsible technical personnel before
installation and start-up. As part of the diverter valve the operating instructions must be available close to
it. People could be seriously injured or killed if the operating instructions are not followed.
Read and observe the operating instructions before using the diverter valve.
Retain the operating instructions and make sure they are available.
Pass on the operating instructions to subsequent users.
2.3 Requirements for persons who work with the diverter valve
Persons could be seriously injured or killed if the diverter valve is used improperly. In order to avoid
accidents, all persons who work with the diverter valve must meet the following minimum requirements.
They are physically capable of controlling the diverter valve.

4.3 Intended use
Diverter valve for the installation of two or more safety valves in a possible combination with bursting discs
for protecting gas storage tanks. The requirements of the pressure equipment directive for redundant or
different types of safety devices are fulfilled with this diverter valve and in combination with safety valves
with the same setting pressure. Additional connections are available on each side for suitable means of
testing.
In the case of servicing the safety valves or replacement of the bursting discs, the side to be serviced is
isolated from 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.

4.9 Lifetime
The user is obligated to use Herose products only for their intended purpose.
In this case, a technical service life may be assumed in accordance with the underlying product standards
(e.g. EN1626 for shut-off valves and EN ISO 4126-1 for safety valves).
The technical service life can be restarted several times through the exchange of wearing parts within the
context of the maintenance intervals, and lifetimes of more than 10 years can be achieved.
If products are stored for a period exceeding 3 years, then the plastic components and elastomer sealing
elements fitted to the product should be replaced as a precautionary measure before installation and use.

5 Assembly
5.1 Installation position
Attention must be paid to the direction of flow.
The installation position is arbitrary.
The preferred installation position should be with the spindle horizontal.
5.2 Notes regarding the installation
Use suitable tools.
Clean tools before the installation
Use suitable transport and lifting equipment for the installation.
Open the packaging only directly before the installation. Freedom from oil and grease for oxygen
(O2)
Diverter valves for oxygen are permanently marked with “O2”.
Only install the diverter valve if the maximum operating pressure and operating conditions of the
plant correspond to the marking on the diverter valve.
Remove protective caps or covers before assembly.
Inspect the diverter valve for dirt and damage.
DO NOT install damaged or dirty diverter valves.
Remove dirt and residues from the pipeline and diverter valve in order to prevent leaks.
Avoid damaging the connections.
The sealing surfaces must remain clean and intact.
Seal the diverter valve with suitable seals.
No sealant (sealing tape, liquid sealing tape) may enter the diverter valve.
Respect the suitability for use with O2.
Connect pipelines in a force-free and torque-free manner.
Stress-free installation.
In order to ensure trouble-free operation, no impermissible static, thermal or dynamic stresses
may be transmitted to the diverter valve. Observe reaction forces.
Temperature-dependent changes in length in the pipework system must be compensated with
expansion joints.
Fasten the diverter valve with the existing threads in the body.
The diverter valve must be protected against dirt and damage during construction work.
Check the leak-tightness.
