Start-up valve for low speed air supply to gradually raise Initial pressure in an air system and for quick exhaust by cutting off air supply Power consumption: 0.35 W Improved flow rate characteristics: Up to 2.3 times C[dm3/(s·bar)]: 9.2 Energy saving: No air flow when the main valve is switched. Improved adjustability at low speed air supply Smaller profile and less work hours due to integrated silencer
