Keystone Butterfly Valve

Butterfly valves excel in providing both true isolation and control capabilities within a single product. Specifically designed for accurate flow and pressure control, these valves are particularly well-suited for applications where positive isolation is a crucial requirement.

YUANDA's butterfly valves are known for their dependable high-cycle service and find applications in a wide range of industries, including Oil & Gas (upstream and downstream), Energy (power and steam distribution), Chemical, Petrochemical, Pulp & Paper, HVAC (Institutional), Water and Waste Water Treatment, as well as in the Life Science and Food & Beverage sectors.

Notably, butterfly valves offered by YUANDA are versatile and cost-effective alternatives to gate, ball, and globe valves. Their ability to replace these traditional valve types makes them an efficient choice for various industrial processes.

YUANDA's butterfly valve series provides a comprehensive solution for industries seeking reliable, high-performance valves capable of serving diverse applications while optimizing operational efficiency and reducing costs.

Because of their spherical shape, these valves are called shut-off valves, and an internal baffle separates the two halves of the valve body. The moving part of the shut-off valve is composed of the valve disc, the valve stem and the hand wheel.
