WAFER BUTTERFLY VALVES

VALVES-BUTTERFLY-VALVES-WAFER-BUTTERFLY-VALVES

Overview

WAFER-STYLE STAINLESS STEEL BUTTERFLY VALVES are compact, lightweight, cost-efficient flow-control valves designed to fit between two pipe flanges. They provide fast quarter-turn operation, minimal pressure drop, and superior reliability for industrial, sanitary, and process water systems.

Wafer butterfly valves are ideal for high-cycle service, tight shutoff, and systems requiring easy installation and maintenance. Ace Stainless supplies wafer butterfly valves in 304/304L, 316/316L, Duplex, and chemical-grade alloys with seat options including EPDM, Viton®, and PTFE.
