Product Advantage

The Two Stem Replaceable Seat CF8M Disc Lug Butterfly Valve (DN400, PN10) offers several advantages, making it a reliable choice for demanding industrial applications.

1. Replaceable Seat: Extends valve life and reduces maintenance costs. You can replace only the seat (not the entire valve) when worn or damaged, saving time and money.

2. Two-Stem Design: Provides better torque distribution and disc alignment. Reduces wear on internal components and enhances valve durability, especially in large-diameter valves.

3. CF8M (316 Stainless Steel) Disc: Excellent corrosion resistance. Suitable for aggressive fluids, seawater, and chemicals—ensures long service life in harsh environments.

4. Lug Type Body: Enables end-of-line service and installation without needing a downstream flange. Ideal for systems requiring isolation or frequent maintenance; simplifies installation and replacement.

5. Bidirectional Sealing Advantage: Seals effectively in both flow directions. Increases versatility and safety in piping system design.

6. Compact & Lightweight: Easier to install and requires less space than gate or globe valves. Reduces load on pipelines and support structures.
