This kind of gate valve not only has the advantages of simple structure and reliable use, but also can produce light elastic deformation to make up for the deviation of the sealing surface angle during machining, and improve machining performance. At the same time, when used in high temperature medium, the gate valve is not easy to be wedged.
 
The valve cover is self-sealing, which can effectively prevent the leakage of the medium, and is safer and more reliable.
