Product Introduction
◆ Product use
The water-sealed gate valve is suitable for use as an opening and closing device on pipelines with a nominal pressure of 100MPa, an operating temperature of 425℃, and a working medium of water, steam, oil and non-corrosive gases, especially for steam engine vacuum condensing systems in thermal power plants.
◆ Product features
1. The S/Z type series adopts double-gate two-way elastic sealing, flexible opening and closing, rapid, and reliable sealing.
2. The product has a simple structure, compact and reasonable, easy maintenance and long service life.
3. For use as an opening and closing device on the pipeline, it must be in a fully open or fully closed state and must not be used to adjust the flow rate.
4. There are two types of valve connection methods: flange and welding, and the driving methods are manual and electric.
