Fluororesin diaphragm valve ideal for abrasive fluids such as slurries.
This is a fluororesin valve designed for chemical piping in semiconductor manufacturing equipment and chemical plants. It features a diaphragm valve structure with low resistance, making it ideal for viscous liquids such as CMP slurry. Due to its low-resistance design, it can offer flow capacity more than twice that of competitors in certain sizes. Additionally, the body shape minimizes liquid accumulation, reducing the risk of contamination.
