Hayward's own total-cost table claims 30+ year thermoplastic valve service life vs under 15 years for metal, and 6x lighter weight — real, testable claims worth checking against a specific mine's duty cycle before assuming a metal butterfly valve is the safer default.
Mining process water and leach circuits are the same aggressive chemistry that drove Asahi to build a whole metal-replacement family in the first place — a butterfly valve here isn't picked for the pipe size alone, it's picked for whether the wetted surface can survive what a metal valve historically couldn't.
Every claim on this page traces to real, vendor-published documentation on file with LibertyCES. Confirm current specifications with the manufacturer before final specification.
