Forged steel bellows gate valve-Bellows valve series-波纹管阀厂家-上海冠环阀门制造有限公司

Product Overview:

Forged steel corrugated pipe gate valves are suitable for Class150~900 and PN1.0~6.0MPa, used to cut off or connect medium in pipelines. By selecting different materials, corrugated pipe gate valves can be suitable for various media such as water, steam, oil, acetic acid, oxidizing media, urea, etc.

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. Ergonomically designed handwheel, with a long service life, easy and convenient operation, making it safer and more reliable.
