Lug-type check valve: a reliable guardian of industrial pipelines

In industrial pipeline systems, check valves are of great significance to maintaining unidirectional flow of media, and Cryogenic Check Valve is a capable member of them.
Its appearance is highly recognizable, and the lugs on both sides of the valve body are a prominent mark. This unique design makes installation easy. The valve can be firmly fixed on the pipeline by simply passing the bolts through the lugs, and it can be flexibly adapted to both horizontal and vertical pipelines. The internal structure mainly includes the valve body, valve disc and valve seat. When flowing forward, the medium pressure easily pushes the valve disc open; once the medium attempts to flow back, the valve disc will be closed instantly under the dual effects of gravity and reverse pressure, resolutely preventing the backflow phenomenon and fully protecting the stability of the pipeline system.
Cryogenic Check Valve has excellent performance. It has a compact structure, small size, and light weight, but it can effectively check and provide solid and reliable protection for the pipeline system. It performs outstandingly in dealing with water hammer problems, can quickly close the valve disc, greatly reduce water hammer pressure, and effectively protect the safety of pipelines and equipment. Based on these advantages, it has been widely used in many fields. In the petrochemical industry, it can prevent the backflow of flammable and explosive media from causing danger; in the water supply and drainage system, it can ensure the normal flow of water and prevent sewage backflow from affecting water quality.
When selecting a model, it is necessary to comprehensively consider the pipeline parameters, medium characteristics and working conditions to accurately match the model. When installing, pay special attention to the correct position and direction to ensure a firm connection. Daily maintenance should not be neglected. Regularly check whether the appearance is damaged, whether the sealing is good, whether the valve disc moves flexibly, clean the internal impurities in time, and lubricate the moving parts. Only in this way can the lug-type check valve continue to play a role stably and ensure the smooth operation of the industrial pipeline system for a long time.
