Product Description
RYCOME Air Actuator Butterfly Valve China Manufacturers Electric Actuator Butterfly Valves ANSI 150LB Standard 3 Inch Flanged Butterfly Valve
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.
Flange Butterfly Valve
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 Steps1. Place the valve between the two pre-installed flanges, and pay attention to the neat alignment of the bolt holes
2. Gently insert four pairs of bolts and nuts into the flange holes, and tighten the nuts slightly to correct the flatness of the flange surface,
3. Fix the flange on the pipeline by spot-welding
4. Remove the valve
5. Completely weld the flange on the pipeline
6. install the valve after the welding point is cooled. Ensure that the valve has enough space in the flange to prevent the valve from being damaged, and ensure that the valve plate has a certain opening
7. Correct the position of the valve and tighten the four pairs of bolts (be careful not to overtighten) and open the valve to ensure that the valve plate can be opened and closed freely then slightly open the valve plate; tighten all the nuts with cross balance; reconfirm that the valve can Open and close freely.
Our Advantages
-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.
-Good Sealing
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.
-Quick Opening and Closing
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.
