1. Principle
The closing piece (disc) moves in the vertical direction of the center line of the passage for full opening and full closing cutoff.
2. Application
Gate valve is mainly used to cut off or connect the medium in the pipeline, generally not used for regulation and throttling.
3. Classification
Gate valves can be divided into: parallel gate valves, wedge gate valves, lift gate valves, rotary rod gate valves, quick opening and closing gate valves, shrink gate valves, flat gate valves, etc. according to different classification methods.
4. Features
The fluid resistance is small, the applicable pressure and temperature range are large, the flow direction of the medium is not limited, and the sealing performance is good.
