Knife Gate Valve PZ73H Product Overview:
Knife gate valve, also known as knife gate valve/Knife shaped gate valves and knife shaped slurry valves 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 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 according to different applications/Knife shaped gate valves, etc. The knife gate valves produced by our factory 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 specialized pipeline systems for food, hygiene, 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 After the emergence of knife gate valves, a large number of general-purpose cut-off valves and regulating valves have been replaced by them.
