Water sealed gate valves are suitable for use as opening and closing devices on pipelines with a nominal pressure of 100MPa, a working temperature of 425 ℃, and working media of water, steam, oil, and non corrosive gases. They are particularly suitable for vacuum condensation systems of steam turbines in thermal power plants.
Product features of water seal gate valve
1. The S/Z series adopts double gate bi-directional elastic sealing, which is flexible, fast, and reliable in opening and closing
2. The product structure is simple, compact and reasonable, easy to maintain, and has a long service life
3. When used as an opening and closing device on a pipeline, it must be in a fully open or fully closed state and should not be used to regulate flow
4. There are two types of valve connection methods: flange and welding, and the driving methods are manual and electric
