Corner safety valve, for compressed air and non-flammable gases, G 1-1/4", DN 18, 8.5 bar, gunmetal

Compressor stations and compressed air networks are protected by a safety valve that works purely mechanically. This version in G 1-1/4" responds at 8.5 bar and discharges 502 m³/h. The nominal size DN 18 determines the discharge cross section. The spring steel spring and the FKM seal withstand the range -20 to +200 °C. The hexagon offers 49 mm across flats.

Advantages

• Connection G 1-1/4" with nominal size DN 18 and 49 mm across flats, so an ordinary spanner is enough for installation.
• Discharge capacity of 502 m³/h of compressed air at DN 18, sufficient for the matching receiver or compressor.
• Fixed set pressure of 8.5 bar, so the protection is unambiguous without any adjustment on site.
• Temperature range of -20 to +200 °C, which covers outdoor installation and hot media alike.
• Gunmetal body, spring steel spring and a seal of FKM, matched to compressed air and other non-toxic, non-flammable gases.
