Manual Wafer Butterfly Valve
Our manual wafer butterfly valve with gear operator features a unique design and compact structure, ideal for space-saving installation in pipelines. The disc adopts a high-strength frame structure, ensuring excellent durability, low operating torque, and reliable performance during frequent open-close cycles.


This butterfly valve is designed with bidirectional sealing, allowing installation without being affected by the medium flow direction. The valve body is coated with epoxy resin, providing superior corrosion resistance and long service life, even in harsh environments.


A wide range of seat materials such as EPDM, NBR, and PTFE are available, making the valve suitable for different media including water, oil, air, gas, and weak corrosive chemicals. The gear-operated handle offers smooth operation, precise flow control, and improved safety for large diameter pipelines.


This wafer type butterfly valve is widely used in water treatment, HVAC systems, chemical plants, oil & gas pipelines, power stations, and general industrial applications where reliable shut-off and flow regulation are required.
