Mark 508 Series – Tank Blanketing Valve
The Mark 508 Gas Back Pressure Regulator is the ideal valve for low-pressure gas regulation. The Mark 508 works in conjugation with the Mark 608 in a low-pressure tank blanketing valve system.
The Mark 508 can be used to vent gas from the tank to prevent the blanketing pressure from rising to a level that could damage the tank while maintaining a small, constant flow to keep the blanket fresh. During filling, the Mark 508 opens to allow gas to escape as the vapor space in the tank grows smaller.
