Protects compressors, receivers and downstream fittings against inadmissible pressure above 21 bar. When it responds, a flow of 15151 m³/h is discharged freely. Built in brass with the G 2" thread and nominal size DN 48.

Advantages

  • Seal in FKM, matched to the set pressure of 21 bar.
  • Set pressure fixed at 21 bar and lead sealed, so no adjustment is possible during operation.
  • Connection thread G 2" with 80 mm across flats, mounted with a standard open end wrench.
  • All metal design in brass, vibration resistant and suitable for continuous use from -20 to +200 °C.
  • Type tested and permanently marked with TÜV-SV...-2003.48.D/G.0,51 CE0036 21 bar.
