Piston/Bellow dual stage high pressure regulator - D230

D230 high pressure cylinder regulator is designed for pure, inert and midly corrosive gas applications requiring a very stable outlet pressure together with a very sensitive set up of this outlet pressure. A cylinder connector is necessary to connect it to the cylinder valve.

Key advantages

Based on the proven S 20 bellows technology
Exceptionally accurate pressure control and stable outlet pressure due to the combination of piston and bellow technology
Compact, Ergonomic and lightweight
Fixed outlet pressure version available
