Safety relief valve G 1-1/4", factory set and sealed, DN 31, 27 bar, brass

Designed for overpressure protection on systems carrying compressed air and other non toxic, non flammable gases. The set pressure of 27 bar is fixed at the factory and the discharge capacity is 12628 m³/h. The brass valve is connected through the G 1-1/4" thread at DN 31.

Advantages

• Discharge capacity of 12628 m³/h at nominal size DN 31, 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 27 bar.
• Compact all metal shape with an overall height H of 215 mm and a height h of 23 mm.
• Connection thread G 1-1/4" with 55 mm across flats, mounted with a standard open end wrench.

Applications

• Compressed air receivers and compressor stations with a permissible working pressure up to 27 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 12628 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...-2003.31.D/G.0,8 CE0036 27 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.
