Bronze Wafer Type Butterfly Valve A wafer type butterfly valves by C-Way Engineering Exports are designed for compact installation, reliable sealing, and efficient flow control in industrial pipelines. Engineered to comply with ANSI/API, DIN/EN, BS, JIS, ISO, and other international standards, these valves offer lightweight construction, low torque operation, and dependable performance across water treatment, HVAC, chemical processing, marine and and general industrial applications.
When your piping layout demands a lightweight, durable and cost-effective isolation solution, our Wafer Type Butterfly Valve delivers. Designed as a concentric butterfly valve to be sandwiched between flanges, this valve eliminates the bulk of traditional gate or globe valves without sacrificing sealing integrity.
At C-Way Engineering Exports, we specialize in providing bubble-tight shutoff valves that meet stringent international safety standards for global infrastructure projects. Our wafer style butterfly valves are manufactured according to internationally recognized ANSI, DIN, JIS and ISO standards, ensuring compatibility with American, European, Australian, Middle Eastern and other global pipeline systems.
