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.
This is a butterfly valve that is designed with flanges on both inlet and outlet faces. A flange is a flat surface that makes a connection between a valve and the pipe very easy and free from leakage.
The butterfly valve flange type has its flanges with holes. The pipe end to be connected to the valve is also designed with a flange and holes of the same size as those on the flanged valve. The valve is secured on the piping system using bolts and nuts. Flanged butterfly valve manufacturers design these valves for flawless and hassle-free performance.
These valves are extensively meant for use in heavy-duty applications as they can endure a tough and harsh environment. This valve is meant for shut-off and throttling applications. The working of this valve is based on a quarter turn of the valve closing element which opens and closes fluid flow as necessary. This type of valve can be operated manually or through actuators.

Flanged butterfly valve is the most common valve connection method in the industrial field. Its production method is generally to design a qualified flange butterfly valve model first, then pour molten steel in a molten state into the model, and perform machining and drilling after it cools down.
The flange connection direction can be installed vertically or horizontally; it can be installed on high-temperature and high-pressure pipelines, and can also be installed on low-temperature and low-pressure pipelines. At the same time, there is no mandatory requirement for the nominal diameter of the pipeline, and the application range is the widest.
Flanged Butterfly Valve Installation Steps
-Simple structure
The Flange butterfly valve is mainly composed of several main components such as the valve body, butterfly plate, valve stem, sealing ring, etc., and its structure is relatively simple. The simple structural design makes flange butterfly valves easy to manufacture, install, and maintain, reducing the probability of failure caused by complex structures.
Flange butterfly valves use elastic sealing rings or metal sealing rings to ensure good sealing performance of the valve. Even under high pressure, high temperature, or corrosive media, flange butterfly valves can maintain a stable sealing effect and avoid leakage problems.
The butterfly plate is a key component of the flange butterfly valve. It only needs to be rotated 90 degrees to complete the switching action.
