1. Application of Knife Gate Valve

1. Mining, iron and steel industry: used for coal, slag slurry, etc;

2. Purification device: used for waste water, mud, dirt and clarified water with suspended solids;

3. Paper industry: used for pulp and feed water mixture of any concentration;

4. Ash removal of power station: used for ash slurry.

2. Performance of Knife Gate Valve

1. Local and remote control, remote position display and remote centralized control can be realized according to user requirements;

2. Light weight: the body is made of carbon steel, stainless steel, duplex stainless steel and other materials. The weight is about 30% - 40% lighter than traditional gate valve, the installation and maintenance are convenient;

3. Compact structure, reduce installation space, reliable sealing performance, eliminate leakage, improve production efficiency;

4. The sealing surface is made of high wear-resistant and corrosion-resistant ceramics, carbide alloy and other materials, and the inlay technology is adopted. It has high corrosion resistance and good wear resistance, so that the valve has long service life.

3. Characteristics of Knife Gate Valve

1. The lifting knife cut wedge sealing surface can scrape off the adhesive objects on the sealing surface and automatically clean up the sundries;

2. Stainless steel wedge can prevent seal leakage caused by corrosion;

3. Carbide alloy, ceramic and other sealing surfaces can ensure the wear resistance and meet requirements of the seal;

4. There is no groove on the sealing surface of the valve body, which will not produce accumulation and ensure flexible opening;

5. Short structure length, economize raw materials;

6. Scientific seal packing design makes the seal safe, effective and durable;

7. The guide block on the valve body makes the wedge move correctly, and the four extrusion blocks ensure the effective sealing of the wedge;

8. The stiffener design of the valve body improves the strength of the valve body;

9. The stainless steel valve stem is durable, and the double thread makes the opening and closing more quickly;

10. Could be adapted to a variety of actuators;

11. Fully enclosed structure can be adopted when the valve diameter is over 150mm, which can better prevent corrosion and leakage;

12. Fluorine rubber sealing surface can be used according to user requirements, which can achieve a good sealing effect and meet the requirements of working conditions;

13. The rubber sealing surface is directly vulcanized in the valve body and will not fall off.
