Safety relief valve G 1", factory set and sealed, DN 20, 50 bar, brass

The spring loaded safety valve limits the pressure in compressed air receivers, compressor stations and pipelines to 50 bar. Once the set pressure is reached it opens and discharges up to 9218 m³/h into the atmosphere. Connection G 1", nominal size DN 20, body in brass.

Advantages

• Set pressure fixed at 50 bar and lead sealed, so no adjustment is possible during operation.
• Discharge capacity of 9218 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 -60 to +225 °C.
• Seal in PTFE, matched to the set pressure of 50 bar.
• Compact all metal shape with an overall height H of 111 mm and a height h of 14 mm.

Technical data

Applications

• Compressed air receivers and compressor stations with a permissible working pressure up to 50 bar
• Pipelines and manifolds for non toxic, non flammable gases with a G 1" connection
• Test benches and machines where a discharge capacity of 9218 m³/h has to be protected
• Workshop networks and plant installations that call for a brass valve body
• Cold installation points down to -60 °C as well as warm areas up to +225 °C

Standards and conformity

The valve is type tested and carries the component marking TÜV-SV...-2055.20.D/G.0,77 CE0036 50 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.
