Overview

Stainless steel electric knife gate valve is suitable for pipelines containing suspended particles, fiber materials such as pulp, sewage, coal slurry, ash and cement mixtures, etc. It relies on a blade shaped gate that can cut through fiber materials to cut off these media. The valve body actually does not have a chamber, and the gate plate rises and falls in the side guide groove, and is tightly pressed against the valve seat by the bottom protrusion. If high medium sealing performance is required, an O-shaped sealing valve seat can be used to achieve bidirectional sealing.

Product Details

Stainless steel electric knife gate valveThe focus of developing new valve products is on the application of new valve materials. Due to the existing corrosion-resistant valve materials not meeting the needs of technological development, the production of ultra-low carbon stainless steel valves is limited. Therefore, the foreign valve industry is accelerating the development of ultra-low carbon duplex stainless steel valves. Ultra low carbon bidirectional stainless steel has the ability to resist point corrosion, intergranular corrosion, and uniform corrosion in environments such as chloride ions, hydrogen sulfide, carbon dioxide, inorganic acids, and organic acids. The commonly used structural forms of regulating valves include straight through single seat valves, straight through double seat valves, sleeve valves, eccentric rotary valves, butterfly valves, fully functional ultra light regulating valves, and ball valves. Based on different usage situations and the characteristics of different structural forms of valves, the structural form of regulating valves should be evaluated from the aspects of regulating performance, applicable temperature, applicable diameter, pressure resistance, applicable medium conditions, cut-off differential pressure, leakage rate, pressure loss, weight, appearance, cost, etc.

Stainless steel electric knife gate valvePerformance characteristics:

1. The valve adopts an integral design, with low fluid resistance and flexible and convenient operation.

2. Quick opening and closing, reliable balance, high degree of automation.

3. The gate is made of austenitic stainless steel, which greatly improves its corrosion resistance and can prevent sealing leakage caused by gate corrosion.

4. The upper sealing filler adopts flexible PTFE, which is reliable in sealing and easy to operate.

5. The gate has the function of a knife, which can cut off various impurities in the medium.

6. The installation height and position are not limited.

7. Adopting explosion-proof electric devices, it can work normally in flammable, explosive, and even toxic gas environments.

8. Equipped with manual control, in case of power interruption, the valve can be manually opened or closed to effectively control the medium and prevent accidents from occurring.

The scope of use is:

1. Mining, coal washing, and steel industry - used for washing coal pipelines, slag slurry pipelines, and ash discharge pipelines;

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

3. Paper industry - used for any concentration of pulp, feed water mixture;

4. Power plant ash removal - used for ash slurry
