  • Risk of over-pressurisation of the regulator body is a safety hazard when using high pressure gas (such as oxygen or argon/CO2) and can cause rupture / explosion of the regulator and or components
  • The pressure relief valve prevents over-pressurisation
  • Valve is built into regulator body internal parts, protecting it from contamination, damage or tampering, to ensure reliable operation

 Regulator Internal Pressure Relief Valve



  • Provides better performance and reliability vs traditional seat designs
  • Sintered filter ensures microscopic particles don't enter the capsule, for longer life
  • Lateral (instead of direct / linear) gas flow protects diaphragm from wear & rupture
  • increased valve surface area minimises flow restrictions and pressure drops
  • Reduced pressure creep (tendency for regulator output pressure & flow to increase as the bottle pressure reduces)
  • Smoother, more consistent and reliable gas delivery flow & pressure
  • Improves weld quality and reduces troubleshooting issues caused / exacerbated by inconsistent gas delivery

Regulator Encapsulated vs Traditional Seat



  • Regulator complies with AS 4267
  • Pressure gauges comply with Australian standards AS 1349 & ISO 5171
  • Inlet connections comply with AS 2473 & ISO 5145
  • Manufactured under ISO-9001 certified quality system
