Pneumatic WCB Tank Bottom Valves With Internal Disc are designed to provide drainage and dead space free shut off for vessels, autoclaves and storage tanks.
The dead space free shut off is accomplished by placing the valve seat flush with the bottom of the tank . This eliminates any build up of medium within the vessel nozzle itself.
Pneumatic WCB Tank Bottom Valves With Internal Disc have Y-type & angle two type constructions. According to the actual operating condition of tanks, the connecting dumping entry has two types: pipe-connecting and flat bottom. If needed ,special surface treatment on the whole valve can be made ,it 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.
BENEFITS
1.This range of pneumatic control tank bottom angle valve is manufactured in y type integrated structure;
2. Short stroke for open/close operation;
3.Both lowering disc type (Also called internal disc , the valve is opened into valve) and rising disc type (also called external disc ,the valve is opened into tank )can be designed .
4.The sealing surface of the valve seat and the valve disc can be made with WC coating .
5. Crust breaking for disc rising type;
6.Disc is designed as external disc.
7.Pneumatic operation can save labour cost .
8.Double action cylinder and sigle action cylider can be selected .
