The ideal valve for low back pressure gas and liquid services. It works in conjunction with the Mark 608, in a low pressure tank blanketing valve system.

A back pressure regulator for use in low pressure gas and liquid services. For critical applications, the Mark 518 can be provided with soft PTFE or Viton seats for ANSI Class VI bubble-tight shutoff. 

In sizes 3/4" through 1-1/4", the Mark 608IS is the ideal valve for low pressure gas regulation. The self-contained low pressure gas regulator is for use on tank blanketing, gas meter inlet pressure regulating, gas burners and other low pressure air and gas applications.

Available in sizes 1-1/2" & 2", the Mark 608 is used on large tank blanketing applications or other low pressure gas regulation.

A double seated, self-operated gas regulator for use in tank blanketing applicatons. The double seated design allows for increased flow and higher pressure drops than similarily sized single seat valve types while maintaining ANSI Class VI shutoff.
