Features

Tight Seal: The rubber wafer butterfly valve uses materials like EPDM, NBR, FTFE, silicone, fluorine rubber, heat-resistant EPDM, and wear-resistant EPDM, ensuring a long service life and improved sealing performance.
High-Strength Valve Disc: The valve disc is of a frame structure, offering high strength and the ability to withstand high flow rates. Additionally, the overall paint design effectively prevents corrosion, allowing for use with different media.
Bidirectional Sealing: Our rubber wafer butterfly valve has bidirectional sealing functionality and can be installed in any direction.
Versatile: Capable of opening and closing in pipeline systems and adjusting flow rates.
Cost-Effective and Low Maintenance: Our cast iron/ductile iron butterfly valves use heavy-duty materials, resulting in cost savings and minimal maintenance requirements.
