2.1 Intended use
The safety valve protects the tank and pipeline systems against impermissible overpressure. 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 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 safety valve.
Retain the operating instructions and make sure they are available.
Pass on the operating instructions to subsequent users.

4.3 Mode of operation
Safety valves protect tanks and pipeline systems against impermissible overpressure. Safety valves
represent the last line of safety for a tank or pipeline system. They should be capable of preventing
impermissible overpressure 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.

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
Vertical
From 20 to 300 bar in the horizontal installation position, with the outlet facing downwards.
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".
Only install the safety valve if the maximum operating pressure and usage conditions correspond
to the marking on the safety valve. Take note of the p-t curve of the valve on the catalogue page
and the resulting areas of use.
Remove protective caps or covers before installing.
Inspect the safety valve for dirt and damage. DO NOT install damaged or dirty safety valves.
Remove any dirt and residues from the pipeline in order to avoid leaks.
Use the entire usable thread length for mounting; at least four thread pitches.
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 reactive forces.
The safety valve is supported by the pipeline system.
The safety valve must be protected against dirt and damage during construction work.
Check leak-tightness after completion of mounting.
Tightening torques
The tightening torques specified by the manufacturer are maximum permissible values at room
temperature and with uniform thread mating. The real torque to be used depends on the screw-in
conditions in the plant and must be specified by the plant operating company.

6 Operation
The maximum permissible pressure loss in the supply pipes 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.
6.1 Liftability (manual actuation for testing)
Liftable safety valves are equipped with an appropriate device above the spring cover.
Make liftable safety valves open at ≥85 % of the set pressure without aids.
Proceed as follows during the initial start-up, after breaks in operation and for checking the
function:
The valve is ready for operation.
1. Pull the lifting lever away from the spring cover until
blow-off of the operating medium is clearly audible.
2. Release the lifting lever again.
