Product Description
The gear operated wafer butterfly valve is a reliable and durable flow control solution widely used in engineering projects and municipal water systems. Its compact wafer-type body is designed for easy installation between flanges, making it suitable for pipeline applications where space is limited and maintenance accessibility is required.
Featuring an aluminum bronze disc, the valve offers improved corrosion resistance compared to standard disc materials, especially in water, seawater, and mildly corrosive media. The EPDM seat provides elastic sealing performance, ensuring stable shut-off and long-term sealing reliability under normal pressure and temperature conditions.
With smooth disc rotation, reduced operating torque, and a worm gear operating mechanism, this valve enables precise flow control and safe operation in water supply networks, HVAC systems, industrial circulation lines, and wastewater treatment facilities. Available in a wide range of sizes and configurations, it can also be customized to meet specific project requirements.
