Product Description
This PTFE seat wafer butterfly valve is designed for reliable shut-off in water and mild corrosive media applications. Featuring an SS304 disc and worm gear operation, the valve provides stable sealing performance, smooth operation, and reduced operating torque under normal pressure and temperature conditions.
Its compact wafer-type body allows easy installation between flanges, making it suitable for pipeline systems where space is limited and maintenance efficiency is important. The PTFE seat offers excellent chemical resistance and low friction characteristics, while the SS304 disc ensures structural strength and corrosion resistance in demanding service environments.
Commonly used in water treatment, HVAC systems, industrial circulation pipelines, and general process applications, this valve delivers dependable performance and long service life. Multiple sizes and configurations are available to meet different project requirements.
