What is a Wafer Butterfly Valve?

A wafer butterfly valve is a compact, lightweight flow control valve that mounts between flanges (PN10/PN16 or ASME Class 150). The central disc rotates via a shaft to open/close the flow, with resilient seats ensuring bubble-tight shutoff. Its design simplifies installation, reduces footprint, and offers excellent cost-performance.

Materials & Standards

Our wafer butterfly valves are manufactured using high-grade materials and adhere to stringent international standards, ensuring durability and optimal performance in diverse applications.

• Body: Ductile Iron (DI), WCB (Carbon Steel), CF8/CF8M (Stainless Steel), Aluminum Bronze (Marine). These materials are selected for their corrosion resistance and mechanical strength.
• Disc: DI/Ni-plated, CF8/CF8M, Aluminum Bronze (Sea water). Discs are precision-machined for optimal flow control and sealing.
• Shaft: SS 410/SS 304/SS 316. High-strength stainless steel shafts ensure reliable operation and resistance to wear.
• Seat/Liner: EPDM, NBR, PTFE, Viton (service-dependent). Resilient seats provide bubble-tight shutoff and chemical compatibility for various media.
• Standards: Adherence to API 609 (Butterfly Valves: Double Flanged, Lug- and Wafer-Type), EN 593 (Industrial valves – Metallic butterfly valves), ISO 5752/EN 558 (Face-to-face and centre-to-face dimensions of metal valves for use in flanged pipe systems), IS flange drillings and ASME Class 150 compatibility ensures interchangeability and global acceptance.
• Actuator Interface: ISO 5211 top flange for direct mounting of gearboxes and actuators, providing versatile automation options.
• Design Practice: MSS SP‑67 (Butterfly Valves) for butterfly valve geometry and performance, guaranteeing robust design.
• Coatings: Fusion-bonded epoxy (FBE) or marine-grade coatings for superior corrosion resistance in harsh environments.
• Testing: EN 12266‑1 (Industrial valves – Testing of metallic valves – Pressure tests, test procedures and acceptance criteria – Part 1: Pressure tests, test procedures and acceptance criteria for the industrial valves specified in the European Standards) hydrostatic (body/seat) with zero visible leakage for resilient seats, ensuring leak-proof operation.
