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.

Industrial applications such as power generation, mining and chemical industries use gate valve. What makes it useful is that the design limits flow barriers. In addition, there is minimal pressure drop. This kind of valve can also be used when the pressu

Gate valves and globe valves are the two most common types of valves in industrial applications. Both have made great contributions to any industrial service. They may look similar, but the functions of these valves are different.
View More
The gate valve is designed for fully open or fully closed service. They are installed in the pipeline as isolation valves and should not be used as control or regulating valves.
View More
Resilient seat gate valves are used for purification and pumping of sewage, fire fighting systems, irrigation, industrial pipelines, etc. It has minimal head loss, 100% water tightness and full bore.

Ball valve is a form of right-angle rotary valve, which uses a hollow, perforated and rotating ball to control it. It is open when the hole of the ball is aligned with the hole of the ball, and it is closed when it is rotated 90 degrees by the valve handl
View More
Globe valves are considered the industry standard for control valves because they are good at regulating flow, while ball valves are more suitable for on/off control without pressure drop.
