Key features

The ball valve with FEP lining layer has extremely high chemical stability and can be used for any strong corrosive properties except''molten alkali metal and elemental fluorine''.

Using a full bore,floating ball structure,the valve can be closed without leakage within the entire pressure range,facilitating ball purging and pipeline maintenance of the pipeline system.

The ball of the hoist and the stem are cast as a whole,eliminating the possibility of the stem rushing out of the pressure bearing part due to pressure changes,fundamentally ensuring the safety.

The structure is compact and reasonable ,with the smallest inner cavity space of the body ,reducing medium retention.

In addition,the special molding process makes the sealing surface have a good density,and the combination of herringbone ring PTFE packing makes the valve achieve zero leakage.

The two-piece and three-piece structure can adapt to various pipeline systems and operating conditions with different requirements.

The three-piece ball valve allows the main body to be separated from the bodies on both sides,enabling rapid online replacement and maintenance.

Product Q&A

Q:What is difference between two-piece & three-piece Q41F46 fluorine-lined ball valve?

Two-piece:Compact structure,competitive price.For maintenance,the whole valve must be removed from pipeline.Suitable for general chemical service. Three-piece:Split-body design.The middle cartridge can be maintained on-line without removing valve from piping.Easy replacement of ball & seats.Recommended for critical process lines,higher cost than two-piece type.

Q:Temperature&pressure rating,suitable media?

Nominal pressure PN10 / PN16;Working temp:-20~180. Resistant to most acids, alkalis,brines and organic solvents.Not for molten alkali metal & elemental fluorine.

Q:Can fluorine-lined ball valve do flow regulation?

Standard version is for ON/OFF shut-off only.Continuous throttling under partial-open position is not recommended.For modulating service,V-notch ball is required.

Q:What parameters required for order?

Model number, two-piece or three-piece,DN,PN,body material(WCB/CF),lining F46,F4,PFA,actuator accessories,process media & temperature.

Q:Installation tips?

1.Protect fluorine-lined flange face against scratch and impact. 2. Tighten flange bolts diagonally and evenly. 3. Clean pipeline before installation to avoid particle damage. 4. Do NOT use valve as throttling device under partial-open.
