Hand operated spiral gate

[Essential information]
Manual spiral gate valve and electric spiral gate valve are usually used in the unloading machine. The diameter of the manual spiral gate valve is matched with the feed inlet of the unloader. There are two kinds of square and circular ones.

[Standard parameter]

[Valve features]
1, the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section.
2, simple structure, small size, light weight.
3, reliable and reliable, the current gate valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used.
4. easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control.
5, easy maintenance, simple valve structure, sealing ring is generally active, disassembly and replacement are more convenient.
6, in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface.
7, gate valve for a wide range of diameter from small to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.

[Adaptive condition]
       Spiral gate is the main control equipment of a powder, crystal and grain material and small volume of material throughput, widely used in metallurgy, mining, building materials, food, chemical and other industries to control the rapid flow changes or cut off.
