Diaphragm single stage high pressure regulator with balanced valve - S800

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.

Key advantages

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
The increase in the useful lifetime of the regulator
