2.1 Intended use
The safety valve protects the vessel 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
mounting 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 vessels and pipework systems against impermissible excess pressure. Safety
valves represent the last line of safety for a vessel or pipework system. They should be capable of
preventing impermissible excess 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
mounting 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 or the rules and standards of
the American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code Section VIII,
Division I.

4.9 Lifetime
The user is obligated to use Herose products 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 synthetic material components and
elastomer sealing elements fitted to the product should be replaced as a precautionary measure before
mounting and use.

5 Assembly
Other assembly steps may be necessary depending on the plant and type of safety valve. In the following
instructions only the major assembly steps are summarised. The instructions are intended only for coarse
orientation. The gasket manufacturer's data must be observed. Safety valves that are subject to special
cleaning regulations may only be unpacked shortly before assembly. When unpacking, it must be ensured
that the packaging is intact up to this point and that the safety valve is not contaminated. In addition, it
must be ensured that the cleanliness requirements are also met during the assembly and that the safety
valve is not contaminated.

5.2 Notices regarding the mounting
Use suitable tools.
Open-ended spanners,
Torque wrench.
Clean tools before the mounting.
Open the packaging only directly before the mounting.
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 mounting.
Check the safety valve for dirt and damage.
DO NOT install damaged or dirty safety valves.
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.
Connect pipelines in a force-free and torque-free manner.
Stress-free mounting.
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 drop in the inlet lines to the safety valves may not exceed
the 3% pressure difference between the response pressure and superimposed back pressure on
the safety valve.
Vibrations are to be avoided.
Check the following points prior to start-up:
All mounting 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 cap.
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: Pull the lifting knob / ring upwards until blow-off of the
operating medium is clearly audible.
Step 2: Release the lifting knob / ring.
Step 1: Pull the lifting lever away from the spring cap until
blow-off of the operating medium is clearly audible.
Step 2: Release the lifting lever again.
