Description
Protects compressors, receivers and downstream fittings against inadmissible pressure above 28 bar. When it responds, a flow of 13080 m³/h is discharged freely. Built in brass with the G 1-1/2" thread and nominal size DN 31.
Advantages
- Set pressure fixed at 28 bar and lead sealed, so no adjustment is possible during operation.
- Discharge capacity of 13080 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 28 bar.
- Compact all metal shape with an overall height H of 215 mm and a height h of 23 mm.
Applications
- Compressed air receivers and compressor stations with a permissible working pressure up to 28 bar
- Pipelines and manifolds for non toxic, non flammable gases with a G 1-1/2" connection
- Test benches and machines where a discharge capacity of 13080 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 28 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.
