The lug butterfly valve’s design is similar to a 3-piece ball valve in that one end of the line can be taken off without having an effect on the opposing side. Lug butterfly valve can be made by using threaded inserts, flanges, along with two sets of lugs that don’t utilize nuts since each flange features its own bolts. It is also important to note that you don’t need to shut down the entire system in order to clean, inspect, repair, or replace a lug butterfly valve.

What are the characteristics of the lug butterfly valve?

The lug butterfly valve has small size with light weight.

A lug butterfly valve is easy to operate and install.

The elastic seal of lug butterfly valve is produced by torque.

The unique design of three-way eccentricity of lug butterfly valve enables frictionless transmission between the sealing surfaces and prolongs the service life of the lug butterfly valve.

The wedge-shaped design makes the lug butterfly valve have an automatic sealing function that is closer and tighter. The sealing surface has compensation and zero leakage.

The material of replacement parts of lug butterfly valve can be applied to various media.

The lug butterfly valve can be equipped with pneumatic and electric devices according to user requirements to meet the needs of remote control and program control.

What should be known about the lug butterfly valve?

The driving mode of the lug butterfly valve can be manual, worm gear, pneumatic and electric. The connection mode of lug butterfly valve can be flange and butt clamp. The structure of lug butterfly valve can be single eccentric, center line, double eccentric and triple eccentric. The sealing structure of lug butterfly valve can be soft seal and hard sealed. The pressure range is from PN0.1 to 10Mpa. The nominal diameter is from DN40mm to 2000mm. The material of lug butterfly valve can be cast steel or stainless steel. Due to the wide range of use of lug butterfly valves, the same lug butterfly valve has different collocations in different occasions and working conditions.

The butterfly plate of the lug butterfly valve is installed in the diameter direction of the pipeline. In the cylindrical passage of the lug butterfly valve body, the disc-shaped butterfly plate rotates around the axis, and the rotation angle is between 0° and 90°. When the rotation reaches 90°, the lug butterfly valve is in a fully open state.

What is the development of the lug butterfly valve?

The lug butterfly valve industry is an important branch of our general machinery. Lug butterfly valves are widely used in petroleum, chemical, metallurgy, electric power, urban construction, environmental protection and other industries as key equipment for fluid control. At present, the lug butterfly valve production industry is in a very favorable development opportunity.

Investment in fixed assets has gradually expanded, especially the projects such as West-East Gas Transmission, West-East Electricity Transmission, and South-to-North Water Diversion projects, which require a large number of lug butterfly valves. 

With the entry of WTO, the lowering of the international trade threshold and the adjustment of product structure in developed countries, China is gradually becoming the world's largest processing plant. The processing and production of lug butterfly valve products is facing greater room for development.

Learn more about lug butterfly valve can know the detailed information about lug butterfly valve and the trend of lug butterfly valve industry. In the process of butterfly valve development, a number of very powerful companies have emerged, such as Tianjin Worlds Valve Co., Ltd. Our company knows how to innovate while developing, and will also go out in the process of introducing lug butterfly valve. Whether from quality or price, or delivery time, we can help customers to open up a further and larger market, it is wise to choose us as your business partner.
