Butterfly valves are 1/4-turn shut-off valves that open and close by rotating a disc to block and adjust the flow of fluid in pipes. They have a simple structure and low operating torque, so they are mainly used in large-diameter pipes such as water and sewage systems, water purification plants, and drainage pump stations. They can be driven manually, electric, hydraulically, or pneumatically, allowing for operation suited to on-site conditions.

This product is designed with durability and maintainability in mind, minimizing uneven wear during repeated opening and closing and maintaining stable water-tight performance. In addition, various sheet materials can be applied depending on the usage environment.

• Rubber sheet: Suitable for general water supply and low-pressure environments, excellent economic efficiency

• Metal sheet: Response to high-pressure and foreign substance environments, semi-permanent lifespan

• Silicone sheet: Enhanced heat and chemical resistance and long-term durability, excellent watertightness

Through this, it is possible to respond to various water quality conditions such as tap water, sewage, raw water, and rainwater, and secures the reliability and operational versatility required for public infrastructure facilities
