5.1 Installation position
With regard to the installation position, pay attention to the arrow showing the flow direction. When
installing the angle valve in a horizontal pipeline, a vertical position of the stem is recommended
(handwheel at the top) or an inclination of up to 65° from the vertical.
5.2 Notices regarding the mounting

Use suitable tools.

Allen keys of sizes 6, 8 and 10;

Open-ended spanners;

Torque wrench;

TIG welding machine;

Oxy-fuel 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
)
Angle valves for oxygen are permanently labelled with “O
2
”.

Only install the angle valve if the maximum operating pressure and operating conditions of the
plant correspond to the marking on the valve.

Remove protective caps or covers before mounting.

Check the angle valve for dirt and damage.
DO NOT install a damaged or dirty angle valve.

Avoid damaging the connections.
The sealing surfaces must remain clean and intact.

Seal the angle valve with suitable seals.
No sealant (sealing tape, liquid sealing tape) may enter the angle valves.
Respect the suitability for use with O
2
.

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 angle valve. Observe reaction forces.

Temperature-dependent changes in length in the pipework system must be compensated with
expansion joints.

The angle valve is supported by the pipework system.

Detailed installation instructions are included for angle valves with pneumatic or electric actuator-
unit.

Driven angle valves: Mounting/dismounting the bonnet in the centre position of the actuator.

The angle valve must be protected against dirt and damage during construction work.

Remove any transport locks such as blocking bushing (optional).

