Rising Disc Type Tank Bottom Angle 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 shut off for reactors, vessels, autoclaves and storage tanks. Rising disc type means that the valve is opened into the tank . 

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.

The series of tank bottom valve has two constructions: Y-type & angle type. According to the actual operating condition, the dumping entry has two types: pipe-connecting and flat bottom. If needed ,special surface treatment on the whole valve makes the surface hardness more than HRC 60, this can ensure the sealing reliability and avoid scarring. Moreover, a rotation-resistant device is set to ensure that the valve stem only has straight line motions, and no revolving motions. The driving manners of the valve include hand driving, electric ,driving, pneumatic and gear driving. Both rising disc type (the valve is opened into tank) and lowering disc type (the valve is opened into valve) can be designed.

BENEFITS


1.This range of manual control tank bottom angle valve is manufactured in  y type integrated structure;

2. Short stroke for open/close operation;

3.lowering disc type (the valve is opened into valve) can be designed if needed.;

4.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.

5. Crust breaking for disc rising type;

6.Disc is designed as external disc.
