The butterfly valve is made from GGG25 cast iron, known for its exceptional strength and corrosion resistance. The material's enhanced durability makes this valve ideal for applications that require resistance to chemicals, high pressures, and extreme temperatures.
The soft and hard back seat feature ensures a tight seal, preventing any leakage and ensuring smooth, precise flow control. The back seat provides a flexible seal that conforms to the disc, ensuring a reliable, secure closure.
This butterfly valve features a wafer design that is easy to install and requires minimal space. It can be installed directly between pipe flanges without the need for additional brackets or supports. The disc design also allows for efficient operation because the disc opens and closes easily, reducing energy consumption and extending the life of the valve.
Whether used in water treatment plants, HVAC systems or industrial process applications, our soft-backed and hard-backed cast iron wafer butterfly valves deliver superior performance and reliability. It meets international standards and undergoes rigorous quality inspections to ensure that every valve leaving our factory meets the highest quality standards.
