Lug Type Check Valve: A Reliable Guardian of Industrial Pipelines

In industrial pipeline systems, check valves are key components to ensure unidirectional flow of media, and lug type check valves are one of the most popular ones.
Lug Type Check Valve has a unique appearance, with lug structures on both sides of its valve body. This design is not only convenient for installation, but also allows the valve to be firmly connected to the pipeline by bolts passing through the lugs, and can be flexibly installed in horizontal or vertical pipelines. From the internal structure, it is mainly composed of a valve body, a valve disc and a valve seat. When the medium flows forward, the fluid pressure pushes the valve disc to open and pass smoothly; once the medium has a tendency to flow back, the valve disc will quickly close under the action of gravity and reverse pressure, effectively preventing backflow and ensuring safe and stable operation of the pipeline system.
Lug Type Check Valve has significant performance advantages. It has a compact structure, small size, and light weight, but it can check efficiently and provide reliable protection for the pipeline system. It performs well in water hammer protection, can quickly close the valve disc, greatly reduce water hammer pressure, and protect pipelines and equipment. For this reason, it is widely used in many fields such as petrochemicals, water supply and drainage, and HVAC. For example, in petrochemical production, it can prevent the backflow of flammable and explosive media from causing safety accidents; in urban water supply and drainage systems, it can ensure the normal transportation of water flow and avoid sewage backflow.
When selecting, it is necessary to accurately select according to pipeline parameters, medium characteristics and working conditions. During installation, it is necessary to pay attention to the correct position and direction and firm connection. Daily maintenance is also indispensable. Regularly check whether the appearance is damaged, whether the sealing is good, whether the valve disc can move flexibly, clean the internal impurities in time, and lubricate the moving parts to allow the lug-type check valve to continue to function stably.
