316SS in continuous brine or sea water service is a chloride-pitting risk over time — the standard reason Crane locks a PFA or PTFE liner between the chloride stream and the ball valve's structural metal rather than relying on the stainless surface alone.
Chloride pitting is a slow, easy-to-miss failure mode compared to acid corrosion — Crane's PFA/PTFE-lined ball valve line exists specifically because the lining, not the structural body alloy, is what actually has to survive continuous brine contact.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
