Assembly
5.1
Installation position
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 keys of sizes 6, 8, 10, 14, 19
Open-ended spanners
Torque wrench
Welding machine
Clean tools before fitting.
Use suitable transport and lifting equipment for the mounting.
Open the packaging only directly before the mounting. Free of oil and grease for oxygen (O
Valves for oxygen are permanently marked with "O
Take note of the HEROSE information sheet "O
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.
Remove dirt and residues from the pipeline and valve in order to prevent leaks.
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.
Respect the suitability for use with O
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
expansion joints.
The valve is supported by the pipework system.
Detailed user information for actuator powered globe valves and attachments with safety function
(sensors, switches, solenoid valves, etc.) must be readily available.
Driven valves: Mounting/dismantling the bonnet in the centre position of the actuator.
The valve must be protected against dirt and damage during construction work.
Remove any transport locks such as blocking bushing (optional).
Check the leak-tightness.
