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.

The gate valve is a valve that completely restricts the flow of fluid and provides a full-diameter valve without changing the direction. The valve disc is appropriately called a gate here and is moved into the fluid at right angles by a threaded shaft wor

In the shut-off valve, the flow of water is controlled by a movable mandrel, and the flow of water is restricted by lowering the mandrel to a fixed valve seat.

The manual gate valve is operated by a simple handwheel to raise the valve stem and gate. When closed, the gate rests on a seat ring, both of which are specially treated to provide a reliable closure.

For decades, globe valves have been considered the industry standard for control valves. They are designed with a stem that moves up and down inside the valve to control flow. They are usually used in hot and cold water coils, and larger models are usuall

These shut-off valves must not be used for on/off service because it is impossible to achieve a tight seal. The disc in the valve can be completely removed from the flow path, or the flow path can be completely closed.
View More
When the handle wheel is turned clockwise, steam and steam move down through the fluid flow, and the gate is squeezed between the two valve seats, so that no fluid leakage occurs when the valve is completely closed.

The gate valve cannot be opened and closed quickly. To fully open or close the wheel or gearbox actuator, the shaft should be rotated to the number of fully open revolutions. The number of full-open revolutions is equal to the pitch.

The ball valve is designed to contain a ball in the valve. There is a hole in the middle of the sphere, and when the hole is aligned with the two ends of the valve, flow will occur. When the valve is closed by rotating the ball 90 degrees, the hole is per

A three-way ball valve is a three-way valve that allows fluid to flow to an alternative path to the hydraulic system. It allows fluid to enter and exit the valve through more than one port.

The globe valve is also a member of the linear motion valve family. Its functions include stopping and starting media and regulating the flow of media. Due to its design, the shut-off valve can provide a tight seal with less chance of leakage.

The valve cover provides a leak-proof closure to the body. The threaded valve stem part will pass through a hole that has a thread similar to the valve cover, and the valve stem with the threaded part extends into the same hole as the valve cover thread.
View More
The gate valve has a closing/closing mechanism. There is an upward internal gate device that allows the medium to flow and closes the valve downward. A distinctive feature of the gate valve is its straight passage, which reduces pressure loss and is easy
