Corner safety valve, for saturated steam and compressed air, G 1", DN 16, 15.0 bar, gunmetal

In steam and compressed air systems the safety valve is the last element of pressure protection and has to work without auxiliary power. This corner valve in G 1" responds at 15.0 bar and is fixed to that setting. Through DN 16 it discharges 670 m³/h of compressed air. The EPDM seal and the gunmetal body permit temperatures of -40 to +150 °C. The width across flats at the hexagon is 40 mm.

Advantages

• Gunmetal body, spring steel spring and a seal of EPDM, matched to steam, compressed air and other non-toxic, non-flammable gases.
• Fixed set pressure of 15.0 bar, so the protection is unambiguous without any adjustment on site.
• Corner design with 35 mm face-to-centre length and 80 mm overall height, so the valve adds little to a vessel wall.
• Discharge capacity of 670 m³/h of compressed air at DN 16, sufficient for the matching receiver or compressor.
• Type tested and marked with the component identification TÜV-SV...-312.16.D/G.0,28 CE0036 15 bar, which simplifies the acceptance of the plant.

Technical data

Applications

Steam boilers to TRD group 1 with a permissible pressure of 15.0 bar. Heat exchangers and steam manifolds with connection G 1". 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...-312.16.D/G.0,28 CE0036 15 bar. It is supplied with a fixed setting only, so the set pressure of 15.0 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.
