Tank Bottom 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. 

Features

1. Both Y type and angle type discharge valve can be designed according to your pipe installation; 

2. Both flat bottom type and pipe connection type tank bottom valve can be designed. 

3. Both rising disc type (the valve is opened into tank) and lowering disc type (the valve is opened into valve) can be designed. 

4. Short stroke for open/close operation;
