Corner safety valve, for compressed air and non-flammable gases, G 3/4", DN 13, 6.5 bar, gunmetal

Every compressed air receiver has to be protected against inadmissible overpressure. This corner safety valve opens at 6.5 bar and blows off 206 m³/h without any control system taking action. The connection is G 3/4" and the nominal size DN 13. A gunmetal body and a seal of FKM allow temperatures of -20 to +200 °C. The height above the connecting face is 70 mm.

Advantages

• Connection G 3/4" with nominal size DN 13 and 32 mm across flats, so an ordinary spanner is enough for installation.
• Discharge capacity of 206 m³/h of compressed air at DN 13, sufficient for the matching receiver or compressor.
• Fixed set pressure of 6.5 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.

Technical data

Applications

Protection of compressed air receivers whose permissible working pressure is 6.5 bar. Compressor stations with connection G 3/4" and a flow rate up to 206 m³/h. Compressed air networks in workshops and production where the protection has to work without auxiliary power. Retrofitting of existing receivers whose safety valve in DN 13 is to be replaced.

Standards and conformity

The valve is type tested and carries the component identification TÜV-SV...-312.13.D/G.0,28 CE0036 6,5 bar. It is supplied with a fixed setting only, so the set pressure of 6.5 bar cannot be altered. A setting certificate to 3.1 is available on request.
