Corner safety valve, for compressed air and non-flammable gases, G 2", DN 25, 14.0 bar, gunmetal

Large compressed air receivers and headers call for protection with a sufficient discharge capacity. This corner valve with DN 25 and connection G 2" releases 1534 m³/h at a set pressure of 14.0 bar. The body is made of gunmetal, the spring of spring steel and the seal of FKM. The permissible temperature range runs from -20 to +200 °C. The overall height is 155 mm and the face-to-centre length 54 mm.

Advantages

• Temperature range of -20 to +200 °C, which covers outdoor installation and hot media alike.
• Fixed set pressure of 14.0 bar, so the protection is unambiguous without any adjustment on site.
• Discharge capacity of 1534 m³/h of compressed air at DN 25, sufficient for the matching receiver or compressor.
• Connection G 2" with nominal size DN 25 and 68 mm across flats, so an ordinary spanner is enough for installation.
• Corner design with 54 mm face-to-centre length and 155 mm overall height, so the valve adds little to a vessel wall.

Applications

Protection of compressed air receivers whose permissible working pressure is 14.0 bar. Compressor stations with connection G 2" and a flow rate up to 1534 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 25 is to be replaced.

Standards and conformity

The valve is type tested and carries the component identification TÜV-SV...-312.25.D/G.0,28 CE0036 14 bar. It is supplied with a fixed setting only, so the set pressure of 14.0 bar cannot be altered. A setting certificate to 3.1 is available on request.
