Low Pressure Regulators > Mark 608 Series




![]() |
The Mark 608 Gas Pressure Regulator 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. The 1/2" and 2" size MK608 valves are for use on large tank blanketing applications or 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. The MK608 comes standard with an extra large diaphragm to give set point control as low as 2.0" w.c. (4,98 mbar). In addition, the "S" pattern body design allows for high flow capacity and also gives the option of having bubble tight shutoff. |
