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 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 globe 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 globe 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 Notices regarding the mounting
Use suitable tools.
Allen keys of sizes 6, 8, 10, 14, 19;
Open-ended spanners;
Torque wrench;
Welding machine;
Clean tools before the mounting.
Use suitable transport and lifting equipment for the mounting.
Open the packaging only directly before the mounting. Free from oil and grease for oxygen (O2).
Valves for oxygen are permanently labelled with “O2”.
Only install the globe valve if the maximum operating pressure and operating conditions of the
plant correspond to the valving marking on the globe valve.
Remove protective caps or covers before mounting.
Check the globe valve for dirt and damage.
DO NOT install damaged or dirty globe valves.
Avoid damaging the ends of the body.
The sealing surfaces must remain clean and intact.
Seal the globe valve with suitable seals.
No sealant (sealing tape, liquid sealing tape) may enter the globe valves.
Respect the 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 globe valve. Observe reaction forces.
Temperature-dependent changes in length in the pipework system must be compensated with
expansion joints.
The globe valve is supported by the pipework system.
Detailed installation instructions are included for globe valves with actuators.
Driven globe valves: Mounting/dismounting the bonnet in the centre position of the actuator.
The globe valve must be protected against dirt and damage during construction work.
Remove any transport locks such as blocking bushing (optional).
Check the leak-tightness.
