Safety relief valve G 1", factory set and sealed, DN 20, 43.5 bar, stainless steel 1.4404

Protects compressors, receivers and downstream fittings against inadmissible pressure above 43.5 bar. When it responds, a flow of 8045 m³/h is discharged freely. Built in stainless steel 1.4404 with the G 1" thread and nominal size DN 20.

Advantages

• Discharge capacity of 8045 m³/h at nominal size DN 20, sufficient for protecting correspondingly sized generators.
• Connection thread G 1" with 41 mm across flats, mounted with a standard open end wrench.
• All metal design in stainless steel 1.4404, vibration resistant and suitable for continuous use from -60 to +225 °C.
• Set pressure fixed at 43.5 bar and lead sealed, so no adjustment is possible during operation.
• Compact all metal shape with an overall height H of 111 mm and a height h of 14 mm.

Applications

• Compressed air receivers and compressor stations with a permissible working pressure up to 43.5 bar
• Pipelines and manifolds for non toxic, non flammable gases with a G 1" connection
• Test benches and machines where a discharge capacity of 8045 m³/h has to be protected
• Systems with increased demands on the corrosion resistance of material 1.4404
• 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 43,5 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.
