pneumatic bottom tank valve(referred to as Tank valve, Angle bottom valve, Bottom drain valve, Flush mount valve etc) are designed to provide drainage and dead space free shutoff for reactors, vessels, autoclaves and storage tanks. The dead space free shutoff is accomplished by placing the valve seat flush with the bottom of the vessel. This eliminates any buildup of product within the vessel nozzle itself.
1. This range of manual control tank bottom angle valve is manufactured in y type integrated structure;
2. Air cylinder operation is usual for saving labor;
3. Short stroke for open/close operation;
4. Both Rising Disc Type (the valve is opened into tank) and lowering disc type ((the valve is opened into valve) can be designed by Quanshun valve ;
5. The sealing surface of the valve seat and the valve disc is made of over laying cemented carbide or painted with tungsten carbide. The auxiliary line sealing guarantee the reliability of the sealing performance.
6. Crust breaking for disc rising type.
