Safety relief valve G 1-1/4", factory set and sealed, DN 31, 2.2 bar, brass

The spring loaded safety valve limits the pressure in compressed air receivers, compressor stations and pipelines to 2.2 bar. Once the set pressure is reached it opens and discharges up to 1335 m³/h into the atmosphere. Connection G 1-1/4", nominal size DN 31, body in brass.

Advantages

• Discharge capacity of 1335 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 2.2 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 2.2 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 1335 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.0,76 CE0036 2,2 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.
