Safety relief valve G 1", factory set and sealed, DN 20, 9.5 bar, brass

Designed for overpressure protection on systems carrying compressed air and other non toxic, non flammable gases. The set pressure of 9.5 bar is fixed at the factory and the discharge capacity is 1887 m³/h. The brass valve is connected through the G 1" thread at DN 20.

Advantages

• Connection thread G 1" with 41 mm across flats, mounted with a standard open end wrench.
• Type tested and permanently marked with TÜV-SV...-2055.20.D/G.0,77 CE0036 9,5 bar.
• Set pressure fixed at 9.5 bar and lead sealed, so no adjustment is possible during operation.
• Discharge capacity of 1887 m³/h at nominal size DN 20, sufficient for protecting correspondingly sized generators.
• All metal design in brass, vibration resistant and suitable for continuous use from -20 to +200 °C.

Applications

• Compressed air receivers and compressor stations with a permissible working pressure up to 9.5 bar
• Pipelines and manifolds for non toxic, non flammable gases with a G 1" connection
• Test benches and machines where a discharge capacity of 1887 m³/h has to be protected
• Workshop networks and plant installations that call for a brass valve body

Standards and conformity

The valve is type tested and carries the component marking TÜV-SV...-2055.20.D/G.0,77 CE0036 9,5 bar together with the CE identification number 0036. It is supplied exclusively with a fixed setting and lead seal. A certification to the ASME Boiler and Pressure Vessel Code, Section VIII Div. 1 and a setting certificate to 3.1 are available on request.
