Is the Through shut-off valve with GZ BSP, EWO suitable for non-flammable gases like nitrogen at working pressures up to 40 bar?

Yes. The Through shut-off valve with GZ BSP, EWO is suitable for nonâflammable gases such as nitrogen at working pressures up to 40 bar, provided the pressure falls within the specified range for the valveâs internal diameter (working pressure: 25â40 bar depending on DN). It is designed for air installations and explicitly allows use with nonâflammable, nonâtoxic gases (nitrogen, CO2, helium, argon, etc.). Materials (brass body, AISI 304 stainless steel ball, NBR stem sealing) and the manual ball closure provide reliable sealing across the stated operating temperature range (â10Â°C to +90Â°C). Ensure the selected DN variant supports your required maximum working pressure and that system conditions (temperature, chemical compatibility with NBR) match the valveâs ratings.

Can the Through shut-off valve with GZ BSP, EWO be used in air installations at temperatures down to -10Â°C?

Yes. The Through shut-off valve with GZ BSP, EWO can be used in air installations at temperatures down to -10Â°C. Its specified operating temperature range is -10Â°C to +90Â°C, it is intended for air installations and compatible with non-flammable, non-toxic gases, and its materials (brass body, AISI 304 ball, NBR stem sealing) support the stated range.

Can the Through shut-off valve with GZ BSP, EWO be manually operated to fully stop flow at various pipe diameters?

Through shut-off valve with GZ BSP, EWO can be manually operated to fully stop flow across various pipe diameters. The valve is designed for manual closure: turning the knob moves the ball into a fully sealed position, stopping medium flow. Performance depends on DN (internal diameter): working pressure rating varies by diameter (25â40 bar), and full shut-off is achievable within the specified operating temperature range (â10Â°C to +90Â°C). Materials (brass body, AISI 304 stainless steel ball, NBR stem sealing) and the BSP external thread design support reliable sealing for air and non-flammable, non-toxic gases (e.g., nitrogen, CO2, helium, argon). Ensure the valveâs DN and corresponding pressure rating match your system requirements and flow direction follows the arrow on the body for correct installation.

Additional information

Material	B – brass (bronze)

The inline shut-off valve with BSP external 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 closure of the shut-off valve is achieved 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.
