Tank Blanketing Regulators > Mark 608IS Series (3/4" - 1-1/4" sizes)
 |
The Mark 608IS 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 Mark 608IS is normally open. Increases in the outlet pressure are sensed through the aspirator causing the large elastomer diaphragm to rise, which moves the plug toward the seat. As outlet pressure decreases, the diaphragm moves don and moves the plug away from the seat to increase flow. The lever, which connects the stem to the diaphragm, amplifies diaphragm forces for tighter shutoff. |
