Q: The CLEAN PVC UNION BALL VALVE I bought is not compatible with another one I have. A: ┼ The CLEAN PVC UNION BALL Valve and the UNION SOCKET come in “A-TYPE” (the old model) and “B-TYPE” (the new model).      These two types are not compatible with each other.  ┼ On the other hand, the SOCKET TYPE from 65A to 100A is compatible with one another.   To Distinguish from A-TYPE to B-TYPE:  One is stamped with FLOW, and the other is not.
