Is the Through-hole shut-off valve with BSP female thread, EWO compatible with gases like nitrogen, CO2, helium, and argon?

Yes. The Through-hole shut-off valve with BSP female thread, EWO is compatible with non-flammable, non-toxic gases including nitrogen, CO2, helium, and argon. Designed for air installations and similar gas systems, it features a brass body, AISI 304 stainless steel ball, and NBR stem sealing for reliable, leak-proof performance. It operates manually via an ergonomic knob, is flow-direction marked, and supports working pressures from 25 to 40 bar (depending on DN) and temperatures from -10°C to +90°C—making it suitable for these gases in typical industrial applications.

Can the Through-hole shut-off valve with BSP female thread, EWO be safely used with non-flammable, non-toxic gases such as nitrogen, CO2, helium, and argon in pneumatic systems?

Yes. The Through-hole shut-off valve with BSP female thread, EWO is suitable for safe use with non-flammable, non-toxic gases such as nitrogen, CO2, helium, and argon in pneumatic systems. Designed for air installations and explicitly compatible with these gases, it features a robust brass body and an AISI 304 stainless steel ball for corrosion and wear resistance. Manual operation via an ergonomic knob provides positive shut-off as the ball moves to a fully sealed position, and the NBR stem sealing minimizes leakage to maintain system integrity. The valve supports working pressures from 25 to 40 bar (depending on DN) and temperatures from −10°C to +90°C, making it appropriate for a wide range of industrial environments. Ensure the selected DN and pressure rating meet your system requirements and follow proper installation and maintenance practices.
