FEP PFA PTFE Lined Flush Bottom Valve Specification:

FEP PFA PTFE Lined Flush Bottom Valve Features:
1. Corrosion resistance: It is different from ordinary up-spread and down-spread discharge valves, and can withstand the corrosion of almost all media (including concentrated nitric acid and aqua regia);
2. Good sealing resistance: special cone spool structure is used to open and close the seal;
3. The material has no residue and should not be crystallized: the valve chamber and the tank body are integrated structures;
4. FEP PFA PTFE Lined Flush Bottom Valve Can be equipped with different modes of operation: manual, pneumatic, electric, hydraulic, gear, etc.
5. Easy to operate, open freely, flexible and reliable movement; The spool assembly and maintenance is simple, the sealing structure is reasonable, and the sealing plate replacement is convenient and practical.

FEP PFA PTFE Lined Flush Bottom Valve Working Principle:
1. The upward FEP PFA PTFE Lined Flush Bottom Valve opens the valve upward movement (the spool moves outside the valve body), and the opening is that the valve needs to overcome the medium force, and the opening moment is larger than the closing moment. The upward opening and closing stroke is small, and the installation height is small. Upspread type for use with agitator FEP PFA PTFE Lined Flush Bottom Valve.
Note: The size of the inlet flange is the same as the size specification of the outlet flange or the size specification is different.
2. The downward expansion type FEP PFA PTFE Lined Flush Bottom Valve is the valve disc (plunger) downward movement of the valve to open (the valve core moves inside the valve body), the direction of movement when opened is the same as the medium force, so the opening is smaller than the closing torque. Large opening and closing stroke, high installation height. Underspread discharge to the reactor of the frame anchor agitator.
Note: The inlet flange size can only be larger than the outlet flange size.
