Corner safety valve, for compressed air and non-flammable gases, G 1-1/4", DN 18, 12.0 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 12.0 bar and discharges 688 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

• Temperature range of -20 to +200 °C, which covers outdoor installation and hot media alike.
• Fixed set pressure of 12.0 bar, so the protection is unambiguous without any adjustment on site.
• Discharge capacity of 688 m³/h of compressed air at DN 18, sufficient for the matching receiver or compressor.
• Connection G 1-1/4" with nominal size DN 18 and 49 mm across flats, so an ordinary spanner is enough for installation.
• Corner design with 40 mm face-to-centre length and 100 mm overall height, so the valve adds little to a vessel wall.

Applications

Pressure vessels in plant engineering with nominal size DN 18. Protection of headers with a discharge capacity of 688 m³/h. Test rigs and experimental setups limited to 12.0 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 12 bar. It is supplied with a fixed setting only, so the set pressure of 12.0 bar cannot be altered. A setting certificate to 3.1 is available on request.
