Options
Valve
The standard 3570 Series does not come with an outlet valve. The diaphragm valve is the 4370 Series.
Cross Purge
• Eliminates the escape of hazardous gases when changing cylinders
• Reduces danger of contamination from atmospheric moisture and oxygen
• Minimizes the amount of gas lost during cylinder changes
• All stainless steel construction
• 4360 Series Quarter-Turn Diaphragm Valves used throughout
