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. FEP PFA衬里球阀的结构紧凑且合理，内壁非常光滑。必威体育娱乐betway阀体是通过精确铸造产生的，具有高强度和光滑的外观。PTFE填料用于实现阀门的零泄漏。

Application Precautions of FEP PFA Lined Ball Valve:

1. FEP衬里球阀的施用温度不得超过150°C。必威体育娱乐betwayFEP（F46）的材料可以在短时间内为150°C，但长期工作温度应以低于120°C的控制。否则，FEP材料将易于软化和变形，从而导致阀泄漏。
PFA衬里的球阀可以在150°C°C必威体育娱乐betway长时间使用，在180°C短时间内使用。

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.
