Corner safety valve, for compressed air and non-flammable gases, G 1-1/4", DN 18, 3.9 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 3.9 bar and discharges 255 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
- Fixed set pressure of 3.9 bar, so the protection is unambiguous without any adjustment on site.
- Gunmetal body, spring steel spring and a seal of FKM, matched to compressed air and other non-toxic, non-flammable gases.
- Connection G 1-1/4" with nominal size DN 18 and 49 mm across flats, so an ordinary spanner is enough for installation.
- Type tested and marked with the component identification TÜV-SV...-312.18.D/G.0,28 CE0036 3,9 bar, which simplifies the acceptance of the plant.

Applications
Pressure vessels in plant engineering with nominal size DN 18. Protection of headers with a discharge capacity of 255 m³/h. Test rigs and experimental setups limited to 3.9 bar. Installation in tight spaces where the corner design with 40 mm face-to-centre length saves room.
Standards and conformity
The valve is type tested and carries the component identification TÜV-SV...-312.18.D/G.0,28 CE0036 3,9 bar. It is supplied with a fixed setting only, so the set pressure of 3.9 bar cannot be altered. A setting certificate to 3.1 is available on request.
