Mark 608 Series – Low-Pressure Gas/Tank Blanketing Regulator

The 1-1/2″ and 2″ size Mark 608 valves are suitable for large tank blanketing applications and other low-pressure gas regulation.In a tank blanketing application, the Mark 608 is used to control the flow of the blanketing gas into the tank to maintain the proper positive pressure. Once the blanket has been established, a small flow of nitrogen is continually admitted to the tank to keep the blanket fresh.

Mark 518 Series – Double Seated Tank Blanketing

The Mark 518 is a back-pressure regulator for use in low pressure air and gas services. With a selection of six pressure ranges, set points can be chosen to control back-pressures from 1″ w.c. to 7 psi (3mbar to 0,5 bar). As a standard feature, the MK518 is provided with soft seals for ANSI Class VI shutoff. The valve is also leak-proof under vacuum conditions.
