Lug Type Butterfly Valve

The lug butterfly valve is a commonly used industrial valve, which is relatively simple in construction and easy to install and maintain. It usually consists of a valve body, a valve disc, a valve stem, a sealing material, and a valve stem handle. In use, the valve plate is rotated by rotating the stem handle, so as to realize the fluid control in the pipeline. For this reason, lug butterfly valves are also known as rotary butterfly valves.

The lug butterfly valve is characterized by the off-axis structure of the valve stem, so that the valve plate can move up and down with the rotation trajectory of the valve stem, so as to ensure the sealing performance. The disc is usually round or oval in shape, and the stability of the disc is maintained by a groove in the inner wall of the valve body, while also preventing it from over-rotating in use. The lug butterfly valve usually controls the position of the valve plate by the fluid pressure in the pipeline, so it opens and closes very quickly and has the characteristics of high efficiency.

The sealing performance of the lug butterfly valve is one of its most important features. In use, a seal on the stem is used between the body and the disc to achieve a sealing effect. These seals are usually made of a variety of materials such as fluoroelastomer, butyl rubber, PTFE, etc., which have the properties of corrosion resistance, high temperature resistance, and low temperature resistance. When selecting a sealing material, it is necessary to select it according to the characteristics of the fluid medium and the environment in which it will be used.

Lug butterfly valves are often used in pipes where small differential pressures can be controlled, such as water supply systems, sewage treatment systems, air conditioning systems, chemical processing, etc. It is usually suitable for pipes with large flow rates because it plays a role in controlling the flow rate. In addition, lug butterfly valves are relatively simple to install and maintain, so they are widely used in a variety of fields.

To sum up, lug butterfly valves have a wide range of application value in industrial piping systems. Its simple, efficient and easy-to-operate characteristics can provide effective solutions for various fluid control. When choosing a brand and model, it is necessary to select according to the characteristics of the use environment and media in order to maximize the benefits of the lug butterfly valve.

Product Detail

 

 

1. Strong corrosion resistance: The main material of the lug butterfly valve is stainless steel, carbon steel, cast iron and other materials, which can resist the erosion of chemicals and corrosive media, and has a long service life.

2. Easy to operate: The operation of the lug butterfly valve is simple, and it can be quickly opened and closed by gently turning the handle or gear, which can meet the requirements of quickly cutting off the pipeline flow.

3. Good sealing: The lug butterfly valve adopts a triple sealing structure, including metal seal, O-shaped seal and packing seal, to ensure no leakage and prevent contaminants and fluid leakage.

4. Light weight: Compared with traditional gate valves, globe valves, etc., lug butterfly valves are light in weight, simple in structure, small in size, easy to maintain and replace, and lower in cost.

5. Wide range of adaptation: Lug butterfly valve can be applied to various pipelines, including oil and gas, chemical, food and other industries, and is widely used in controlling the flow of media, regulating the flow and cutting off the flow of media.
