Tank Blanketing Regulator - Mark 608DS
The Mark 608DS is a double-seated, self-operated gas regulator for use in tank blanketing applications. The double-seated design allows the Mark 608DS to handle increased flow and higher pressure drops than similarly sized single-seat valve types while maintaining ANSI Class VI shutoff. The...
Tank Blanketing/Low Pressure Gas Regulator - Mark 608IS Series
The Mark 608IS gas pressure regulator is ideal 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. The Mark 608IS is normally open. The...
Piloted Tank Blanketing Regulator - Mark 695 Series
The Mark 695 Series piloted soft seat regulator was designed specifically to provide accurate pressure control on very low pressure tank blanketing systems. The pilot operated Mark 695 responds to very small changes in tank pressure by throttling open or closed to maintain the...
Piloted Tank Blanketing Regulator - Mark 695 Series 2"
The 2” Mark 695 is a pilot-operated blanketing regulator designed for high flows, great accuracy, and fast lock-up.
Tank Blanketing Regulator - Mark 695X Series
The Mark 695X Series regulator was designed specifically to provide accurate pressure control on very low pressure tank blanketing systems. The Mark 695X responds to very small changes in tank pressure by throttling open or closed to maintain the desired pressure set point.
Gas Service Regulator - Mark 627 Series
The Mark 627 is a self-operated, pressure-reducing regulator that provides accurate regulation and tight shutoff on low- or high-pressure systems. Use on air, natural gas, or a variety of other gases. The Mark 627 handles inlet pressures up to 2000 psi (137,9 bar). It features a tamper-resistant...
Gas Service/High Pressure Regulator - Mark 630 Series
