Bendix K222390-90 or K22239090 Double Check Valve, model DC-4000, is a genuine Bendix air brake valve. A double check valve lets air from either of two sources feed one shared line, and it passes whichever source is at the higher pressure. Inside, a movable shuttle or disc is pushed against the lower-pressure inlet to seal it off, so the weaker source cannot bleed back out. Not sure this is the valve for your brake plumbing? Call us and we will help you confirm fit.
