Is the Angle shut-off valve with BSP GZ, EWO suitable for use with oxygen or other oxidizing gases?

No. The Angle shut-off valve with BSP GZ, EWO is intended for air installations and for non-flammable, non-toxic gases (e.g., nitrogen, CO2, helium, argon). It is not specified for oxygen or other oxidizing gases. Materials used (brass body, stainless steel AISI 304 ball, NBR stem sealing) and the product description do not confirm compatibility with oxygen service; oxygen applications require components and seals approved and cleaned for oxygen to avoid fire/explosion risk. Therefore do not use this valve with oxygen or other oxidizing gases unless the manufacturer explicitly certifies oxygen compatibility and provides appropriate cleaning and materials data.

Can the Angle shut-off valve with BSP GZ, EWO be installed in high-pressure pneumatic systems up to 40 bar?

Yes. The Angle shut-off valve with BSP GZ, EWO can be installed in high-pressure pneumatic systems up to 40 bar, provided the selected DN (internal diameter) variant is rated for that pressure. It is designed for air and non-flammable, non-toxic gases, has a brass body, stainless steel AISI 304 ball, NBR stem sealing, and a working pressure range from 25 to 40 bar depending on DN, with operating temperatures from -10Â°C to +90Â°C. Ensure the chosen DN matches the system pressure and follow installation and safety guidelines.

Can the Angle shut-off valve with BSP GZ, EWO be used with flammable or toxic gases?

No. The Angle shut-off valve with BSP GZ, EWO Format is intended for air installations and may be used with non-flammable, non-toxic gases (e.g. nitrogen, carbon dioxide, helium, argon). It is not specified for use with flammable or toxic gases and therefore should not be used with such media. Materials (brass body, stainless steel AISI 304 ball, NBR stem sealing) and the product description do not qualify it for handling hazardous or combustible gases; using it for flammable or toxic gases could create safety and compliance risks.

Additional information

Material	B – brass (bronze)

The angular shut-off valve with external BSP thread is used to stop the flow of the medium in the installation. It is intended for air installations, and it can also be used with non-flammable and non-toxic gases (nitrogen, carbon dioxide, helium, argon, etc.). The shut-off valve is closed by manually turning the knob, which moves the ball until it is completely sealed. The direction of flow is indicated by an arrow on the valve body. Maximum constant working pressure across the full temperature range. Body material: brass. Ball material: stainless steel AISI 304. Stem sealing: NBR. Working pressure: from 25 bar to 40 bar, depending on the internal diameter DN. Operating temperature: from -10°C to +90°C.
