Rubber Lined Pneumatic Control Flush Bottom Outlet Valve, WCB、LCB、CF8M、CF3M

The pneumatic flush bottom valve is split into upward bottom outlet valve and downward bottom outlet valve.Rubber lined control bottom valve is principally employed for bottom relieve reactors,storage tanks along with other containers.The number of valves are pretty straight forward in structure, and also the surface in touch with the medium is lined with fluorine material, and also the valve is opened up and closed through the cone valve plug structure.

The Features of Lined Pneumatic Control Flush Bottom Valve:

1. Corrosion resistance: It's almost resistant against corrosion of medium (including concentrated nitric acidity and aqua regia), unlike ordinary up-and-lower bottom outlet valves

2. Good sealing: special taper valve core structure can be used to open and shut the seal

3. The fabric doesn't have residue, is difficult to crystallize, and also the valve cavity and also the tank body are integrated structure

4. It may be outfitted with various modes of operation: manual, pneumatic, electric, hydraulic, etc.

5. Convenient operation, free start, flexible movement, simple set up and upkeep of valve core, reasonable sealing structure, convenient and practical sealing plate substitute.

The Structure Principle of Pneumatic Flush Bottom Valve:

1.The upward bottom outlet valve is opened for the valve to move upward (the valve core moves outside the valve body), and the valve is required to overcome the force of the medium, and the closing torque is larger when the valve is opened. The upper opening and closing stroke is small and the installation height is small. The up-up type is used for the discharge of the reactor with the agitator discharge valve. Note: The size of the imported flange is the same as the size of the outlet flange or the size is different.

2. The downward bottom outlet valve is opened for the valve flap (plunger) to move downward (the valve core moves inside the valve body). When it is opened, the movement direction is the same as the force of the medium, so the closing torque is smaller when it is opened. The lower opening and closing stroke is large and the installation height is high.The lower discharge type discharge is discharged from the reaction kettle of the frame type anchor stirrer. Note: The size of the inlet flange can only be larger than the size of the flange.
