ISO 16135 lined ball valve — ASTM Equivalent

Holding a datasheet that specifies ISO 16135 lined ball valve (ISO)? The valve-grade equivalent, its properties, and certified supply of the matching ASTM grade.

What is the ASTM equivalent of ISO 16135 lined ball valve?

ISO 16135 lined ball valve is a ISO designation corresponding to ASTM PTFE / FEP Lining (D1457 / BS 6564) (PTFE / FEP-Lined Valves) for industrial valve service. The full grade data is below - equivalence is by nominal chemistry and mechanical class, so confirm composition and heat-treat condition against the governing standard before substituting in critical service.

PTFE / FEP-Lined Valves - cast form.

Service temperature-40°C to +200°C
Nominal compositionBody: grey cast iron (A126 Cl B) or carbon steel (A216 WCB). Liner: PTFE (CF₂)n - fluoropolymer, or FEP - tetrafluoroethylene-hexafluoropropylene copolymer. No metallic fluid contact.

Typical service: Hydrofluoric acid (dilute) - PTFE is one of few materials resistant to HF; Hydrochloric acid at all concentrations up to 150°C; Sulphuric acid up to 98% at ambient temperature
