Product Features
1. The key component of the corrugated pipe sealed gate valve is the metal corrugated pipe. The lower end is automatically welded to the valve stem assembly, and the upper end is automatically welded to the connecting plate, forming a metal barrier between the fluid medium and the atmosphere to ensure zero leakage of the valve stem.2. The valve disc adopts a conical design, and the sealing surface is streamlined with the medium, resulting in better sealing performance and longer service life.
3. Double sealing design (bellows+packing), if the bellows fails, the valve stem packing will also avoid leakage and comply with international sealing standards.
4. The valve cover comes with a grease fitting, which can directly lubricate the valve stem, nut, and shaft sleeve, unlike traditional methods that only lubricate the threads.
5. Ergonomic design handwheel with long service life, easy and convenient operation, and more safe and reliable
