Safety relief valve G 1", factory set and sealed, DN 20, 8.9 bar, brass

Protects compressors, receivers and downstream fittings against inadmissible pressure above 8.9 bar. When it responds, a flow of 1779 m³/h is discharged freely. Built in brass with the G 1" thread and nominal size DN 20.

Advantages

• Connection thread G 1" with 41 mm across flats, mounted with a standard open end wrench.
• Seal in FKM, matched to the set pressure of 8.9 bar.
• Set pressure fixed at 8.9 bar and lead sealed, so no adjustment is possible during operation.
• Type tested and permanently marked with TÜV-SV...-2055.20.D/G.0,77 CE0036 8,9 bar.
• All metal design in brass, vibration resistant and suitable for continuous use from -20 to +200 °C.
