DR SERIES

High Pressure Gas
Cylinder Regulator

A diaphragm-operated pressure reducing valve engineered for high-pressure gas cylinder outlets — stepping down up to 400 Bar cylinder pressure to a stable, adjustable 0–25 Bar working supply for welding, medical, laboratory and industrial gas lines.

Built-In Protection

Precision Two-Stage Design

  • Inlet filter and pressure gauge fitted as standard per IS 6901
  • Metal diaphragm construction for long service life at high differential pressure
  • Compact bottom-mounting configuration available for cylinder manifolds
  • Adjustable integral safety relief valve protects downstream equipment
Not to be confused with the PB Series air line regulator (0–42 Bar) — the DR is purpose-built for high-pressure gas cylinder outlets up to 400 Bar inlet.
Applications

Where It's Used

The DR Series regulates cylinder-stored industrial and medical gases down to a safe, stable working pressure for welding & cutting stations, laboratory gas supply, medical oxygen manifolds and process gas distribution panels.
