Product Description
Butterfly Valve
is from a family of valves called quarter-turn valves. In operation, the valve is fully open or closed when the disc is rotated a quarter turn. The "butterfly" is a metal disc mounted on a rod. The seal creates a dynamic seal when the disc is rotated into the closed position, the same seat also forms the primary stem seal to prevent Seal through the stem.
Manual butterfly valves can be applied to a variety of flow control systems, Such as food and beverage, brewing, pharmaceutical, and other industries. The valves are easy to install, easy to maintain, many connection options are available and have high dimensional accuracy and surface finish quality.
Unlike electric butterfly valves, it does not require an external power supply or control system. Instead, the valve is opened and closed by manually rotating the valve stem or handwheel.

-Easy to Use
The opening and closing of the valve can be controlled by manually rotating the valve stem or handwheel, without the need for a complex electrical control system.
Since the manual butterfly valve has no electrical or pneumatic components, it can be more stable and reliable in some harsh environments, such as high temperature, corrosion and other conditions.
Manual butterfly valves are suitable for various media, including liquids, gases, steam, etc., and have good adaptability under different temperature, pressure and flow conditions.
The manual butterfly valve has a simple structure and can be manually adjusted as needed. It is highly flexible and facilitates precise control of the flow and pressure of the fluid.
Manual butterfly valves are easy to install and maintain, which can save manpower and time costs.
-Lower cost
Compared to electric or pneumatic butterfly valves, manual butterfly valves have lower manufacturing and installation costs, making them an economical option
