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

The spring loaded safety valve limits the pressure in compressed air receivers, compressor stations and pipelines to 20 bar. Once the set pressure is reached it opens and discharges up to 3786 m³/h into the atmosphere. Connection G 1", nominal size DN 20, body in brass.

Advantages

• Type tested and permanently marked with TÜV-SV...-2055.20.D/G.0,77 CE0036 20 bar.
• Connection thread G 1" with 41 mm across flats, mounted with a standard open end wrench.
• Compact all metal shape with an overall height H of 111 mm and a height h of 14 mm.
• Set pressure fixed at 20 bar and lead sealed, so no adjustment is possible during operation.
• Discharge capacity of 3786 m³/h at nominal size DN 20, sufficient for protecting correspondingly sized generators.

Applications

• Compressed air receivers and compressor stations with a permissible working pressure up to 20 bar
• Pipelines and manifolds for non toxic, non flammable gases with a G 1" connection
• Test benches and machines where a discharge capacity of 3786 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 20 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.
