2 Safety
2.1 Intended use
The safety valve protects the tank and pipework systems against impermissible excessive pressure. The
permissible operating conditions are specified in these operating instructions.
The safety 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
Never exceed the permissible usage limits specified in the data sheet or in the documentation
with regard to pressure, temperature, etc.
Follow all safety instructions and operating procedures in these operating instructions.
Warranty claims against HEROSE GMBH will be rejected if the HEROSE seal is broken by
unauthorised companies.
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 safety valve the operating instructions must be available in their
vicinity. People could be seriously injured or killed if the operating instructions are not followed.
Read and observe the operating instructions before using the safety valve.
Retain the operating instructions and make sure they are available.
Pass on the operating instructions to subsequent users.

4.3 Intended use
Safety valves protect tanks and pipework systems against impermissible excessive pressure. Safety
valves represent the last line of safety for a tank or pipework system. They should be capable of
preventing impermissible excessive pressure when all other upstream regulating, control and monitoring
devices have failed. In order to ensure this operability, safety valves require special attention during their
assembly and maintenance.
A safety valve is a piece of equipment with a safety function for protecting pressure equipment when the
permissible limits are exceeded and is thus subject to Directive 2014/68/EU (Pressure equipment
directive) of the European Parliament and of the Council, article 2, section 4.

5.2 Notes regarding the installation
Use suitable tools.
Open-ended spanners
Torque wrench
Clean tools before the installation
Open the packaging only directly before the installation. Freedom from oil and grease for oxygen
(O2)
Safety valves for oxygen are permanently marked with "O2".
Install the safety valve only if the maximum operating pressure and operating conditions
correspond to the marking on the safety valve.
Remove protective caps or covers before assembly.
Inspect the safety valve for dirt and damage.
DO NOT install damaged or dirty safety valves.
Remove dirt and residues from the pipeline and safety valve in order to prevent leaks.
Avoid damaging the connections.
The sealing surfaces must remain clean and intact.
Seal the safety valve using suitable seals.
No sealant (sealing tape, liquid sealing tape) may enter the safety 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 safety valve. Observe reaction forces.
Temperature-dependent changes in length in the pipework system must be compensated with
expansion joints.
The safety valve is supported by the pipework system.
The safety valve must be protected against dirt and damage during construction work.
Check the leak-tightness.

6 Operation
The maximum permissible pressure loss in the supply lines to the safety valves may not exceed
the 3% pressure difference between the response pressure and external back pressure on the
safety valve.
Vibrations are to be avoided.
Check the following points prior to start-up:
All assembly and installation work are completed.
Compare the material, pressure, temperature and installation position with the layout plan for
the pipework system.
Dirt and residues have been removed from the pipeline and safety valve in order to prevent
leaks.
6.1 Liftability (manual actuation for testing)
Liftable safety valves are equipped with an appropriate device above the spring cover.
Liftable safety valves can be made to open at ≥85 % of the set pressure without aids.
Typical lifting cases are initial commissioning, after breaks in operation and functional testing; the
procedure is as follows:
Step 1: Loosen the lifting knob and pull it upwards until blow-off
of the operating medium is clearly audible.
Step 2: Release the lifting knob and tighten it again.
Step 1: Pull the lifting lever away from the spring cover until
blow-off of the operating medium is clearly audible.
Step 2: Release the lifting lever again.
