5.1 Installation position
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 (O
2
)
Globe valves for oxygen are permanently labelled with “O
2
”.
Take note of the HEROSE information sheet "O
2
instructions".

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.

Remove dirt and residues from the pipeline and globe valve in order to prevent leaks.

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 middle position of the actuator.

The globe valve must be protected against dirt and damage during construction work.
