LT Manual Soft Seal Butterfly Valve With Protruding Ears

Our valve is based on the wafer installation, and the connection with the pipeline flange is achieved through the lug structure on both sides of the valve body. Compared with the traditional flange connection valve, it has significant advantages such as compact structure, convenient installation and small space occupation. When working, the butterfly plate rotates 90° around the valve stem axis to realize the opening, closing and flow regulation functions of the valve. When the butterfly plate rotates to be parallel to the pipeline axis, the valve is fully open and the medium can pass smoothly; when the butterfly plate rotates to be perpendicular to the pipeline axis, the valve is closed to effectively cut off the flow of the medium.

Shengshi Huagong LT lug manual soft seal wafer butterfly valve has this unique structure and working method, making it an efficient and reliable control element in the pipeline system.

Technical parameters

Performance characteristics

1. Compact structure and convenient installation: LT lug manual soft seal wafer butterfly valve adopts wafer installation, without additional flange connection parts, compact structure and small space occupation. During the installation process, just place the valve between the two pipe flanges and clamp and fix it through the stud bolts through the bolt holes on the lugs. The installation process is simple and fast, which can effectively save installation space and time costs. It is especially suitable for pipeline systems with limited space, such as pipeline wells in high-rise buildings and small cabins in ships. At the same time, this installation method makes valve replacement more convenient and reduces the difficulty of maintenance.

2. Small fluid resistance, energy-saving and high efficiency: The straight-through flow channel design inside the valve body makes the flow resistance of the fluid extremely small when passing through the valve. Compared with other types of valves, it can effectively reduce energy loss and reduce the operating cost of the pipeline system. In large-scale fluid transportation systems, this energy-saving advantage is more obvious, which helps to improve the energy utilization efficiency of the entire system and conforms to the development trend of energy conservation and emission reduction in modern industry.

3. Reliable sealing performance: According to different working conditions, soft sealing or hard sealing structure can be selected to ensure that the valve has good sealing performance. Soft-sealed butterfly valves can achieve zero leakage or extremely low leakage, meeting the strict sealing requirements for gas and liquid transportation occasions; hard-sealed butterfly valves are resistant to high temperature and wear, and can still maintain reliable sealing effects under harsh working conditions such as high temperature, high pressure, and medium containing particles. It can be widely used in various complex industrial environments and civil fields, providing strong guarantees for the safe operation of pipeline systems.

4. Flexible operation and precise control: The manual drive mode is simple and intuitive to operate, which is convenient for on-site personnel to open and close the valve; the electric and pneumatic drive modes can realize remote control and automatic operation. By receiving external control signals, the valve opening can be accurately controlled to meet the precise requirements for flow regulation under different working conditions. Whether in the automated control process in industrial production or in the dispatching management of urban water supply and gas supply systems, the lug-on butterfly valve can flexibly respond to control instructions, realize precise fluid control, and improve production efficiency and management level.
