Wafer Type Stainless Steel Butterfly Valve Body CF8 CF8M Duplex

Optimized for high-volume OEM assembly lines, our Wafer Type Stainless Steel Bare Valve Body offers a lightweight, space-saving foundation for industrial fluid control systems.

Unlike lugged versions, the wafer design features smooth centering holes rather than tapped threads. This allows the finished valve to be rapidly clamped between two pipe flanges, significantly reducing overall pipeline weight and installation footprint. Cast from corrosion-resistant CF8, CF8M, and Duplex stainless steel, this bare body is delivered fully CNC-machined and ready for the immediate insertion of your custom seat liners and disc configurations.

Core Foundry Advantages:

• Compact Dimensions: Short face-to-face profile minimizes space requirements in complex piping networks.
• Universal Centering: Smooth alignment holes accommodate multiple flange standards (ANSI, DIN, JIS) simultaneously.
• Cost Efficiency: Reduced casting weight provides a highly economical solution for bulk OEM manufacturing.

Due to its compact and economical footprint, valve brands frequently assemble these wafer bodies for use in:

Commercial HVAC chilled water loops, sanitary food and beverage processing, light chemical distribution, and pharmaceutical utility lines. The CF8/CF8M construction ensures strict compliance with sanitary and anti-corrosion standards.

Q1: What is the main structural difference between this Wafer body and a Lug body?

A: This wafer body features smooth, unthreaded centering holes and relies on the compression between two pipe flanges to stay in place. It is lighter and more economical than a lug body, which uses tapped threads for bolting directly to the pipeline.

Q2: Will these centering holes match my specific flange standards?

A: Yes, our wafer body positioning holes are engineered with universal tolerances to accommodate multiple international flange drilling patterns, including ANSI Class 150, DIN PN10/PN16, and JIS 10K.

Q3: How is the surface finish prepared before shipment?

A: After the investment casting process, all stainless steel bodies undergo professional shot blasting to remove scale, followed by precise CNC machining on the internal sealing surfaces and top mounting pad.
