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 695 Series – Piloted Tank Blanketing Regulator
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 desired pressure set point.
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.
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.
Mark 608BP – Balanced Plug Regulator
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 valve has a 360° orientation, can be installed in any position, and can be easily re positioned while in line. The seat and plug can be inspected without removing body from the line.
Mark 608DS – Double Seated High Capacity Tank Blanketing Regulator
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.
Mark 608IS – Tank Blanketing/Low Pressure Gas Regulator
The Mark 608 IS 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.
Mark 688 Series – Piloted Soft Seat Regulator
The Mark 688 Series piloted soft seat regulator was designed specifically to provide accurate pressure control on very low pressure tank blanketing systems. The pilot operated Mark 688 responds to very small changes in tank pressure by throttling open or closed to maintain the desired pressure set point.
