The reason why it is so popular is because the friction between the sealing surfaces during opening and closing is small, it is more durable, the opening height is not large, it is easy to manufacture, and the maintenance is convenient. Not only for medium and low pressure, but also for high pressure. Its closing principle is that, relying on the pressure of the valve rod, the sealing surface of the valve flap and the sealing surface of the valve seat are closely adhered to prevent the circulation of the medium. The shut-off valve only allows the medium to flow in one direction, and it is directional during installation. The structural length of the shut-off valve is longer than that of the gate valve, and at the same time, the fluid resistance is large. During long-term operation, the sealing reliability is not strong. 1. The valve body is forged as a whole, with high strength, beautiful appearance and reliable material. 2. The middle cavity adopts self-sealing structure, the higher the pressure, the better the sealing. Unique stainless steel self-sealing ring, convenient for disassembly and assembly, reliable sealing. 3. The surface of the valve stem is super dense and wear-resistant, wear-resistant and corrosion-resistant, and the friction of opening and closing is small to ensure that the product does not leak.
