The knife gate valve has a shearing function, which can scrape off the adhesive medium on the sealing surface and automatically remove debris. The stainless steel gate valve can prevent sealing leakage caused by corrosion.

The knife gate valve is suitable for coal, slag discharge, urban sewage treatment, food, paper, medicine, petroleum, chemical and other oil, water, steam pipelines of mine power plants, connecting or cutting cement slurry and gold mine in pipelines, powder, ore, slag, slime, pulp, wood pulp, tailings, fiber, dust, chemical treatment sewage, sedimentation tank, asphalt, silo export, fruit, grain, slaughterhouse wastewater, etc.

1. The stainless steel knife can prevent the seal leakage caused by corrosion, and the fine grinding and polishing treatment can obtain better sealing effect. The bottom of the blade is processed into a blade shape, which has a cutting function for soft materials such as fiber, pulp, and wood pulp, and has a good opening and closing function. A hard PTFE scraper is installed on the upper end of the blade to prevent dust, gravel and other abrasive substances from entering the packing box, which can significantly improve the life of the blade.

2. The stainless steel valve body is durable, the valve body rib design improves the strength of the valve body, and the double head screw help the opening and closing more quickly.

3. The overall stainless steel material can prevent corrosion damage. The valve body and packing culvert are all precision casting. The valve body is made of integral casting. The material can be selected according to user's needs: 304, 316, 316L, WCB, 2Crl3. The sealing ring is made of reinforced PTFE material, which is corrosion resistant, wear resistant, and non-stick slag.

4. Scientific upper sealing stuffing box design makes the upper sealing safe and effective and durable.

5. Short structure length, which can save raw materials, installation space and effectively support pipeline strength.

6. The triangular bracket saves raw materials and guarantees the required mechanical properties.

7. The knife type gate valve can also be arbitrarily selected for the drive mechanism.
