Is your valve going to withstand water's low PH levels (6)

It will not effect the plastic or Stainless Steel ones at all. There is no lead in the other CSV's to worry about either. Even the B series are coated on the inside. Only the CSV1W and CSV1Z would be effected, but then it would take a long time for it to cause a problem.
