High Quality FEP PFA Lined Ball Valve ANSI DIN API JIS

The plug of theFEP PFA lined ball valveis a ball with an O-shaped hole. The ball rotates with the valve stem around the centerline of the valve body to open and close the lined ball valve. The inner wall of body and valve trims are lined with FEP,PFA and other fluorine materials.The special high temperature molding process is adopted to make the sealing surface compact,and the V-type PTFE packing makes the valve reach zero leakage.

TheFEP PFA lined valveis specially designed for the opening and closing control of various highly corrosive medium pipelines, and is widely used in petroleum,chemical,dyeing, pesticide, acid and alkali production industries. It is one of the ideal choices for current anti-corrosion valve equipment.

The Features of FEP PFA Lined Ball Valve:

1.FEP and PFA are white and translucent and are suitable for all corrosive medium. The mechanics, electrical properties and chemical stability are basically the same as those of F4, but the outstanding advantages are high dynamic toughness and excellent weather resistance and radiation.Our factory adopts new FEP and PFA materials,which make the lined ball valves more stable, more resistant to corrosion and more resistant to aging.

2.Using a high-temperature molding lining fluorine process, FEP and PFA lining fluorine materials are put into a specific mold, melted and then molded by a press.The lined ball valve has good sealing performance and pressure resistance.

3.The internal fully-lined fluorine process is used, and any part inside the lined ball valve is isolated from the medium. The valve stem and the ball are integrated. They are simultaneously molded and lined with FEP or PFA to avoid the transmission gap of the valve stem and the ball.

4. The structure of the FEP PFA lined ball valve is compact and reasonable, and the inner wall is very smooth. The valve body is produced by precision casting, with high strength and smooth appearance.It is quick to open and close and easy to operate. PTFE packing is used to achieve zero leakage of the valve.

Application Precautions of FEP PFA Lined Ball Valve:

1. The application temperature of the FEP lined ball valve should not exceed 150 °C. The material of FEP(F46) can be 150 °C for a short time, but for a long time working temperature should be controlled below 120 °C.Otherwise, the FEP material will be easy to soften and deform, resulting in valve leakage.
And the PFA lined ball valve can be used at 150 °C °C for long time and at 180 °C for short time.

2. There should be not negative pressure. The lined ball valve should prevent negative pressure in the pipeline. If there is negative pressure, the fluoroplastic layer which is easy to form the inner cavity of the valve is sucked out (bulging) and unshelled, causing the ball valve fails to open and close.

3. The pressure and pressure difference of the medium should be controlled within the specified range of use. If the pressure is out of range, the lining fluorine layer will be cracked and deformed, causing leakage.

4. For the medium used for the FEP PFA ball valve,there should not be hard particles, impurities and crystals, so as to avoid scratching the fluorine layer during the opening and closing process of the ball valve.

5. It is forbidden to use the lever to open and close the fluorine-filled ball valve. After opening and closing, do not force to close again to avoid premature damage of the fluoroplastic sealing surface.

When selecting various types ofFEP PFA ball valves, users should understand and grasp the operating conditions as much as possible in order to select and use the right valves to improve the service life. In case of exceeding the requirements of the operating conditions, it shall be proposed to the manufacturer, negotiated together, and adopt corresponding countermeasures to solve.
