Safety relief valve G 1", factory set and sealed, DN 20, 7.3 bar, brass

Protects compressors, receivers and downstream fittings against inadmissible pressure above 7.3 bar. When it responds, a flow of 1489 m³/h is discharged freely. Built in brass with the G 1" thread and nominal size DN 20.

Advantages

• Connection thread G 1" with 41 mm across flats, mounted with a standard open end wrench.
• Seal in FKM, matched to the set pressure of 7.3 bar.
• Set pressure fixed at 7.3 bar and lead sealed, so no adjustment is possible during operation.
• Type tested and permanently marked with TÜV-SV...-2055.20.D/G.0,77 CE0036 7,3 bar.
• 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 7.3 bar
• Pipelines and manifolds for non toxic, non flammable gases with a G 1" connection
• Test benches and machines where a discharge capacity of 1489 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 7,3 bar together with the CE identification number 0036.
