Combination Air Bypass/Air Control Valve

The Combination Air Bypass/Air Control Valve (9F491) combines the functions of the air bypass valve (9B289) and the air control valve (9F491) into a single unit. There are two normally closed valves; the non-bleed type Figure 1 and the bleed type Figure 2 all of which look alike. One distinguishing feature will be that the bleed type will have a the percent of bleed molded into the plastic case.
