2.3 Safety
devices
The pressure regulator is equipped with an integrated relief valve to protect the fitting. The versions with
outlet pressures >100 bar do not have a relief valve. The user must ensure there is a suitable safety device
installed downstream!
Note!
The relief valve allows gas that has to be released as a result of an impermissible rise in the
outlet pressure to be blown off.
It does not function as the safety valve for the entire gas supply system.
Caution!
In the event of failure of the pressure regulator and its relief valve, a safety mechanism that
meets the requirements of the regulations for operators must be incorporated to protect
downstream fittings, pressure vessels and pipes from excess pressure.
Danger!
With combustible, toxic, corrosive and other gases that are harmful to health or the environment,
an exhaust pipe must be connected to the relief valve to discharge the gas safely.
The factory setting of the relief valve must not be changed!
Possible hazard
Measures for prevention
Risk of fatal injury!
As cylinder pressure regulators with a purge device are
predominantly used with toxic and/or corrosive gases, it
must be ensured that the purged gases are safely
discharged and disposed of correctly.
Connect a pipe routing the purged gases to a recycling
facility to the waste gas valves of the cylinder pressure
regulator.
Risk of fatal injury!
If oxygen comes into contact with oil or grease, there is a
risk of fire due to a chemical reaction.
Keep all components which come into contact with oxygen
completely free of oil and grease.
Risk of fatal injury!
Gas escaping into the ambient air can ignite; there is a risk
of fire and explosion.
Smoking and naked flames are strictly prohibited in the
vicinity of gas supply systems
