Corner safety valve, for saturated steam and compressed air, G 1-1/2", DN 22, 6.0 bar, gunmetal
Large boilers and vessels need a correspondingly large discharge cross section so that the pressure really falls in a fault case. This corner safety valve with DN 22 and connection G 1-1/2" releases 550 m³/h of compressed air as soon as 6.0 bar is reached. The gunmetal body and the spring steel spring stay dimensionally stable across the range -40 to +150 °C. The overall height is 140 mm.
Advantages
- Fixed set pressure of 6.0 bar, so the protection is unambiguous without any adjustment on site.
- Gunmetal body, spring steel spring and a seal of EPDM, matched to steam, compressed air and other non-toxic, non-flammable gases.
- Connection G 1-1/2" with nominal size DN 22 and 56 mm across flats, so an ordinary spanner is enough for installation.
- Type tested and marked with the component identification TÜV-SV...-312.22.D/G.0,28 CE0036 6 bar, which simplifies the acceptance of the plant.

Applications
Steam boilers to TRD group 1 with a permissible pressure of 6.0 bar. Heat exchangers and steam manifolds with connection G 1-1/2". Vessels operated within the temperature range -40 to +150 °C. Plants where the component identification has to be presented for acceptance.
Standards and conformity
The valve is type tested and carries the component identification TÜV-SV...-312.22.D/G.0,28 CE0036 6 bar. It is supplied with a fixed setting only, so the set pressure of 6.0 bar cannot be altered. A setting certificate to 3.1 is available on request. The version is approved for saturated steam and for steam boilers to TRD group 1.
