The unions enable the valve to be unscrewed and removed from the pipeline, where it can be serviced or checked to see whether it's blocked, and then easily put back in the pipeline where the unions can get screwed back on. The main advantage of a PVC double union ball valve is that it has a full-bore flow all the way through. This means there is nothing to catch any debris that might be coming down in the water or fluid. Therefore, it is highly unlikely to get blocked.
