Product Details

The  Special Tank Bottom Angle Valve For Coal Slurry is designed based on practical situation of the coal chemical industry. During the development of the product, characteristic of the coal slurry has been taken into consideration as well, The stainless steel dump valve is generally installed at the bottom of the coal slurry tank to discharge the medium.

Features
1.Special cleaning device is offered for the valve body of the flange connection valve,which can be used to clean the inside of the product periodically. So caking and blocking of the coal slurry can be avoided.
2.Made of corrosion-resistant material,the inner cavity of the valve body is painted.
3.The sealing surface made of bead weld cemented carbide makes for the longer service of the special dump valve for coal slurry.
4.The anti-rotation mechanism of the dump valve for coal slurry can guarantee the rectilinear motion of the valve stem.
