The flox[on] S Pressure Controi controls the outlet pressure and compensates fluctuations of the inlet pressure. The set value is the target pressure and the real value is the actual pressure at the outlet of the controller. Two standard modifications of the flox[on] S Pressure Control are available: The economy version is useful for standard applications with gases like compressed air, nitrogene or argon. The stainless steel version, free of brass components, can be used in applications like food industry. Based on the swiss technik of mass flow controller of the flox[on] series (see here) FC Technik started a brand new series of pressure controller.
