Butterfly valves with EPDM liners are indispensable in potable water systems, offering a unique blend of compliance, safety, and durability. EPDM’s chemical inertness ensures no contamination, while its elasticity and bond strength guarantee long-term sealing performance. By adhering to global standards like NSF/ANSI 61 and FDA 21 CFR 177, these valves protect public health while reducing lifecycle costs.
