*Knife Gate Valve: The opening and closing component of a knife gate valve is a gate valve, which moves perpendicular to the fluid direction. Manual knife gate valves can only be fully opened and fully closed, and cannot be adjusted or throttled.
This valve is easy to operate and can be opened freely,Flexible and reliable movement; The valve disc assembly and maintenance are simple, the sealing structure is reasonable, and the sealing ring replacement is convenient and practical.
*Knife gate valve drive modes: manual, electric, pneumatic, hydraulic, bevel gear, electro-hydraulic, and pneumatic hydraulic.
*Knife gate valve appearance:Visible pole, hidden poleTwo.
*Knife gate valve material:Cast iron, cast steel, carbon steel, stainless steel, fluorine liningWait.
*Knife gate valve sealing:Hard seal, soft seal, single-sided seal, double-sided sealSeal with various materials.
Entered our country in the 1980s. In less than twenty years, its usage has expanded from ordinary fields to a wider range of industries. Coal selection, gangue discharge, and slag discharge from 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 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 After the emergence of knife gate valves, a large number of general-purpose cut-off valves and regulating valves have been replaced by them. Today, the United States and Japan have the highest usage of knife gate valves.
Work performance and installation：
gate valveIt has the advantages of simple and compact structure, reasonable design, lightweight and material saving, reliable sealing, easy and flexible operation, small volume, smooth channel, low flow resistance, light weight, easy installation and disassembly. It can work normally under working pressure of 1.0MPa-2.5MPa and operating temperature of -29-600 ℃. Knife gate valve has a shearing function on its gate plate, which can scrape off the adhesive on the sealing surface and automatically remove debris. Stainless steel gate plate can prevent sealing leakage caused by corrosion.
