Three-way reversing slurry valveis an inverted process valve developed according to the alumina process, which adopts the design principle of superimposed multi-function valve, and is designed as aone inlet andtwo outletsstructure. Slurry diversion and conduction is realized by changing valve stem structural and seal of upper and lower valve body .

When the valvedisc is closed downward, the lower seal of the valve is closed, and the slurry enters the upper outlet through the valve cavity to realize the reverse process; While thedisc is lifted upwards, the upper seal of the valve is closed, and the slurry enters the lower outlet through the valve cavity to realize the reverse process.So the speed of the alumina dissolution process is greatly improved,more overa lot of production costs is saved for users.



Features

1. The valve isdesigned as one inlet andtwo outlets structure,so the inlet and outlet flow channels have switching functions, and the two flow channels can be opened and closed alternately as needed;

2. Short stroke, fast and convenient opening and closing;

3. Small flow resistance and less medium pressure loss;

4. The sealing surface material adopts WC alloy and other types of cemented carbide, which has high hardness, erosion resistance and long service life;

5. The structure ofinlet andoutlet port can bedesigned asparallel, vertical or inclined;

6. Valve drivingmodel includes manual, electric, pneumatic,worm gear , etc;

Application

Three-way valve slurry valve is installed in front or behind ofthe tank of alumina production.As thevalve is an integral assembly valve,itrealizes the dual or multi-purpose of one valve, whichgreatly optimize the past aluminum oxide plant reverse process installation structure, and also facilitates the mutual cooperation and conversion process of the inverted process system. The valve is widely used in alumina, metallurgy and other industries withslurry medium .
