Electro hydraulic knife type gate valves, also known as electro hydraulic knife type gate valves or electro hydraulic knife type gate valves, are suitable for pipelines containing suspended particles, fiber materials such as pulp, sewage, coal slurry, ash cement mixtures, etc. These media are cut off by a blade shaped gate plate that can cut fiber materials. The valve body actually does not have a cavity, and the gate rises and falls in the side guide groove, and is tightly pressed onto the valve seat by the bottom lug. If high medium sealing is required, an O-ring sealing valve seat can be selected to achieve bidirectional sealing. According to the driving method, it is divided into manual knife type gate valves, pneumatic knife type gate valves, and electric knife type gate valves.
