Product Details

Product Overview:

DMZ973X, DMZ973F, DMZ973H, DMZ973Y, DMZ973W electric concealed stem knife gate valve, also known as knife gate valve/knife gate valve/insert plate valve, knife slurry valve, entered China in the 1980s. In less than twenty years, its usage has expanded from ordinary fields to a wider range of industries. Knife gate valves can be divided into manual knife gate valves, pneumatic knife gate valves, electric knife gate valves, bevel gear knife gate valves, clamp type knife gate valves, flange knife gate valves, chain wheel knife gate valves, electro-hydraulic knife gate valves, manual slurry valves, hydraulic slurry valves, pneumatic slurry valves, spiral gate valves, hidden stem knife gate valves, knife gate valves/knife gate valves, etc. according to different applications. Knife gate valves are used for coal preparation, gangue discharge, and slag discharge in mining power plants. It has developed into urban sewage treatment, from general industrial pipelines to pipeline systems for food, sanitation, medicine, and other industries. The ultra-thin knife gate valve completely solves the difficult problems of high flow resistance, heavy weight, difficult installation, and large footprint of ordinary gate valves, flat gate valves, ball valves, globe valves, regulating valves, butterfly valves, and other types of valves due to its advantages of small volume, low flow resistance, light weight, easy installation, and easy disassembly. After the emergence of knife gate valves, a large number of general-purpose cut-off valves and regulating valves have been replaced by them.

Product Features:

1. Ultra short structural length saves materials and greatly reduces the overall weight of the pipeline system.

2. Occupying a small effective space, it can effectively support the strength of the pipeline and reduce the possibility of pipeline vibration.

3. The gate is made of austenitic stainless steel, which greatly improves its corrosion resistance and can effectively 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 effectively block various impurities in the medium.

Application scope:

Mining and steel industry - used for coal slurry, filter residue slurry, etc.

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

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

Sugar industry - used for sugar beet washing, syrup, juice extraction, fruit juice, etc.

Food industry - used for washing and rinsing equipment, grain conveying equipment, malt extract, etc.

Power plant ash removal - used for ash slurry.
