Standard Features

Packing
PTFE and Graphite Packings are available for all valve types.

Surface Treatment:
Carbon Steel Valves are phosphatized by default.

Pressure Test:
A shell test and a seat test are performed at 1.5 times the max. allowable (working) pressure acc. to EN 12266-1 - P10, P11 and P12 respectively MSS-SP61 at every standard AS-Schneider Needle Type Globe Valve.

Certification:
Inspection certificate 3.1 acc. to EN 10 204 for valve body material and pressure test available on request. The heat resisting materials are available by default with inspection certificate 3.2!

Optional Features

Fugitive Emission Applications:
For Fugitive Emission Applications AS-Schneider is providing bellows sealed valves with safety packing. Choice of Pressure class PN 100 or PN 250 - Suffix P5 or P6.

The bellows are submitted to a 100% Helium leak test. Leak rate: 10-8 mbar l/s.

Optional available are TA-Luft and ISO 15848 solutions. For more details please contact the factory.

Oxygen Service:
AS-Schneider offers an option with Reinforced PTFE Packing cleaned and lubricated for Oxygen Service – Suffix F5:

Pressure-Temperature Rating:
Max. 420 bar @ 60°C
Max. 200°C @ 90 bar

Not every Valve type is available for Oxygen Service.

If you don‘t find your options, please contact the factory.

Attention:
Packing adjustment may be required during the service life of
the valves. Valves that have not been cycled for a period of
time may have a higher initial actuation torque. When delivered
ex factory, the safety packing of the belllows sealed valve is not
fully tightened. In the event of a bellows failure the safety packing
must be tightened in order to avoid fluid leakage.
