Our stainless steel flanged butterfly valves are made of high-quality 304/316 stainless steel, featuring excellent corrosion resistance, high strength and long service life. They are suitable for harsh working conditions such as water treatment, chemical engineering, petroleum, food and medicine, and HVAC systems. This valve features a compact structure, rapid opening and closing, and provides bidirectional sealing performance to ensure zero leakage. It is an ideal choice for fluid control in industrial pipelines.
Product Features
✔ High-quality stainless steel material - The valve body, valve plate and valve stem are all made of 304/316 stainless steel, which is resistant to acid and alkali and rust, and is suitable for highly corrosive media.
✔ Flange connection design - compliant with international standards such as ANSI, DIN, JIS, and GB, it is easy to install and ensures reliable sealing.
✔ Bidirectional sealing performance - Equipped with EPDM, PTFE or metal hard sealing valve seats, it can adapt to different temperatures (-20°C to 200°C) and pressures (PN10-PN40).
✔ Low flow resistance design - The streamlined structure of the butterfly plate reduces pressure loss and improves fluid efficiency.
Flexible operation mode - supports handles, worm gears, pneumatic or electric actuators to meet the requirements of manual/automatic control.
