Key Features & Advantages

1. Wafer Type Design–Compact & Economical

  • Lightweight and Space-Saving–The wafer design eliminates integral flanges, reducing overall weight and allowing installation in tight piping layouts.

  • Fast Installation–Simply center the valve between two standard pipe flanges and tighten the flange bolts. No special tools or complex procedures required.

  • Lower Cost–With less material and simpler machining than lug or flanged designs, wafer valves offer excellent value for general-purpose applications.

 

2. Body Material – Gray Iron (ASTM A126 Class B)

  • Good Strength for General Service–Gray iron provides adequate mechanical strength for Class 150 service in water, oil, and gas applications.

  • Excellent Machinability–The material allows precise casting and tight dimensional tolerances, ensuring reliable flange sealing and smooth operation.

  • Cost-Effective Solution–Gray iron offers an economical material choice for general-purpose industrial applications where high impact resistance is not required.

 

3. Disc Material–CF8M Stainless Steel (AISI 316)

  • Superior Corrosion Resistance–CF8M offers excellent resistance to pitting and crevice corrosion, particularly in chloride environments and seawater.

  • Wide Chemical Compatibility–Suitable for water, wastewater, mild chemicals, acids, and alkalis.

  • Long Service Life–The corrosion-resistant properties of CF8M ensure extended service life even in aggressive environments.

 

4. Seat Material–EPDM (Replaceable)

  • Excellent Water Resistance–EPDM offers outstanding resistance to water, steam, and outdoor weathering, making it ideal for water supply, wastewater, and HVAC applications.

  • Replaceable Design–The seat is mechanically retained, allowing replacement in the field without removing the valve from the pipeline–simply loosen the disc, swap the seat, and reassemble.

  • Wide Temperature Range–Maintains sealing properties from -20°C to +120°C, covering the full range of typical water system operating temperatures.

 

Typical Applications

Thanks to its robust construction and fully customizable material options, this wafer butterfly valve is widely utilized across diverse industries:

  • Water Supply & Distribution–Municipal water mains, pumping stations, distribution networks.

  • Wastewater Treatment–Sewage lines, treatment plants, effluent systems.

  • HVAC Systems–Chilled water, hot water, cooling tower systems.

  • Fire Protection–Fire water lines, sprinkler systems.

  • Industrial Processes–General industrial water lines, cooling water, process fluids.

  • Irrigation–Agricultural and landscape irrigation systems.
