Installation position

With regard to the installation position, pay attention to the flow direction arrow. Installation is only
permitted in the flow direction. When installing the valve in a horizontal pipeline a vertical position of the
spindle is recommended (hand lever at the top) or an inclination of up to 65° from the vertical.
5.2 Notes regarding the installation

Use suitable tools.

Allen keys of sizes 6, 8, 10, 14, 19;

Use suitable transport and lifting equipment for the installation.

Open the packaging only directly before the installation. Freedom from oil and grease for oxygen
(O )
2
Valves for oxygen are permanently marked with "O

Only install the valve if the maximum operating pressure and usage conditions of the plant
correspond to the marking on the valve.

Remove protective caps or covers before assembly.

Inspect the valve for dirt and damage.
DO NOT install a damaged or dirty valve.

Avoid damaging the connections.

Stress-free installation.

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.

The valve must be protected against dirt and damage during construction work.

Remove the transport lock if fitted.

Check the leak-tightness.
