4.9 Lifetime
The user is obliged to use HEROSE products exclusively 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
5.1 Installation position
≤ DN150
With regard to the installation position, pay attention to the arrow showing the flow direction. When
mounting the valve in a horizontal pipeline, a vertical position of the operating mechanism or an inclination
of up to 65° from the vertical is recommended.
DN200
With regard to the installation position, pay attention to the arrow showing the flow direction. When
mounting the valve in a horizontal pipeline, a vertical position of the operating mechanism or an inclination
of up to 45° from the vertical is recommended.
5.2 Fitting Notice
 Use suitable tools.
 Allen key
 Open-ended spanners
 Torque wrench
 Welding machine
 Clean tools before fitting.
 Use suitable transport and lifting equipment for installation.
 Open the packaging immediately before installation. Free of oil and grease for oxygen (O2).
 Valves for oxygen are permanently marked with "O2".
 Take note of the HEROSE information sheet "O2 instructions".
 Only install the valve if the maximum working pressure and operating conditions of the plant
correspond to the valving marking on the valve.
 Remove protective caps or covers before mounting.
 Check the valve for dirt and damage.
 DO NOT install damaged or dirty valves.
 Avoid damaging the body end.
 The sealing surfaces must remain clean and intact.
 Seal the valve with suitable seals.
 No sealant (sealing tape, liquid sealant) may enter the valves.
 Observe suitability for use with O2.
 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 valve. Observe reaction forces.
 Temperature-dependent changes in length in the pipework system must be compensated with expan-
sion joints.
 The valve is supported by the pipework system.
