Safety relief valve G 1", factory set and sealed, DN 20, 33 bar, stainless steel 1.4404

The spring loaded safety valve limits the pressure in compressed air receivers, compressor stations and pipelines to 33 bar. Once the set pressure is reached it opens and discharges up to 6140 m³/h into the atmosphere. Connection G 1", nominal size DN 20, body in stainless steel 1.4404.

Advantages

• Seal in PTFE, matched to the set pressure of 33 bar.
• Compact all metal shape with an overall height H of 111 mm and a height h of 14 mm.
• Connection thread G 1" with 41 mm across flats, mounted with a standard open end wrench.
• Type tested and permanently marked with TÜV-SV...-2055.20.D/G.0,77 CE0036 33 bar.
• Set pressure fixed at 33 bar and lead sealed, so no adjustment is possible during operation.

Applications

• Compressed air receivers and compressor stations with a permissible working pressure up to 33 bar
• Pipelines and manifolds for non toxic, non flammable gases with a G 1" connection
• Test benches and machines where a discharge capacity of 6140 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 33 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.
