Safety relief valve G 1-1/4", factory set and sealed, DN 31, 7 bar, brass

The spring loaded safety valve limits the pressure in compressed air receivers, compressor stations and pipelines to 7 bar. Once the set pressure is reached it opens and discharges up to 3575 m³/h into the atmosphere. Connection G 1-1/4", nominal size DN 31, body in brass.

Advantages

• Discharge capacity of 3575 m³/h at nominal size DN 31, sufficient for protecting correspondingly sized generators.
• Connection thread G 1-1/4" with 55 mm across flats, mounted with a standard open end wrench.
• All metal design in brass, vibration resistant and suitable for continuous use from -20 to +200 °C.
• Set pressure fixed at 7 bar and lead sealed, so no adjustment is possible during operation.
• Compact all metal shape with an overall height H of 215 mm and a height h of 23 mm.

Technical data

Applications

• Compressed air receivers and compressor stations with a permissible working pressure up to 7 bar
• Pipelines and manifolds for non toxic, non flammable gases with a G 1-1/4" connection
• Test benches and machines where a discharge capacity of 3575 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...-2003.31.D/G.0,8 CE0036 7 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.
