PFA Lined Discharge Ball Valve

PFA Lined Discharge Ball Valve

• J&O FEP PTFE PFA lined discharge ball valve is mainly used for the bottom discharge of reactors, storage tanks and other containers. By means of the bottom flange of the valve, FEP PTFE PFA lined discharge ball valve is connected to the bottom of storage tanks and other containers, thus eliminate the residual phenomenon of process media usually at the outlet of containers.
• The working principle of FEP PTFE PFA lined discharge ball valve is to make the valve unblocked or blocked by rotating ball.With full port, floating ball structure, the valve can be closed without leakage in the whole pressure range, which is more convenient for the pipeline system to sweep the line through the ball and pipeline maintenance.The ball is integrated with stem by casting (forging), which will not cause the possibility of stem impact in the bearing parts due to pressure change;
• The lined discharge ball valve which is lined with corrosion resistant fluorine plastic can withstand any corrosive medium,except for "molten alkali metal and element fluorine.
• It is widely used in the industries of chemical, petroleum, food, iron and steel smelting, papermaking, water and electricity, environmental assurance and so on.
• There are various driving modes, such as manual, worm gear, electric, pneumatic, hydraulic.And the lining material can be FEP, PTFE PFA, etc.
• It has the advantages of compact and reasonable structure, small body cavity space and reduction the retention of media.In addition, the special molding process results in good sealing surface density.
