Corner safety valve, for saturated steam and compressed air, G 3/4", DN 13, 8.5 bar, gunmetal

A steam boiler must not exceed its permissible working pressure, not even when the control system fails. This corner safety valve opens at a fixed set pressure of 8.5 bar and releases the excess pressure to atmosphere. The connection is G 3/4" with a nominal size of DN 13. The discharge capacity is 262 m³/h of compressed air. A gunmetal body, a spring steel spring and a seal of EPDM cover the temperature range of -40 to +150 °C.

Advantages

• Fixed set pressure of 8.5 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 3/4" with nominal size DN 13 and 32 mm across flats, so an ordinary spanner is enough for installation.
• Type tested and marked with the component identification TÜV-SV...-312.13.D/G.0,28 CE0036 8,5 bar, which simplifies the acceptance of the plant.

Applications

Steam boilers to TRD group 1 with a permissible pressure of 8.5 bar. Heat exchangers and steam manifolds with connection G 3/4". 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...-312.13.D/G.0,28 CE0036 8,5 bar. It is supplied with a fixed setting only, so the set pressure of 8.5 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.
