This kind of gate valve is not only characterized as simple structure and reliable usage, like the single-disc wedge gate valve, but also able to create slight flexible deformation to compensate the deviation of the sealing face angle generated during processing, thus improving the process performance. In addition, when it is used under a high temperature medium, the disc is also not liable to be wedged.
