Diaphragm single stage high pressure regulator with balanced valve - S800
Manufacturer product images · for reference

S800 high pressure cylinder regulator is designed for purity gases and high-pressure applications requiring high flow and precise outlet pressure, such as laser applications. It is also suited for nuclear research departments where the precision of the outlet pressure and high flow are essential. A cylinder connector is necessary to connect it to the cylinder valve.
- Best-in-class pressure control with Balanced-Valve Technology allowing :
- Minimization of the effect of inlet pressure fluctuations on outlet pressure
- The delivery of a very stable outlet pressure and flow even with high flow
- Dedicated food-grade version with full material compatibility according to EC1935/2004 available
