WCB FEP-Lined Vertical Stem Flanged Discharge Ball Valve are equipped with a layer of fluoroplastic coating on both the valve body and valve core surfaces that come into contact with the fluid. This effectively isolates the corrosive media from any metal contact, providing excellent protection against corrosion for all metal materials.This Bottom Ball Valve have 3 to 5 mm thick lining, which is anti-corrosive a food-grade.
FEP-Lined Vertical Stem Flanged Discharge Ball Valve features a valve body and inner parts that come into contact with the fluid, which are lined with fluoroplastic through a high-temperature molding process. Additionally, the inner cavity of the metal valve body undergoes gear machining to ensure complete bonding between the lining material and metal, thereby enhancing both service life and performance.
The Advantages:
1. Corrosion-resistant: It can withstand the corrosion of various media, including concentrated nitric acid and aqua regia.
2. High flow capacity,minimizes the dead area above the ball where it tends to close. And facilitate the free flow and quick discharge of the liquid or slurry through the valves.
3. Excellent sealing performance: Utilizes a combination structure of imported V-shape packing gland to ensure zero external leakage.
4. Minimal leakage due to the soft sealing with fluoroplastic of the valve core and seat.
5. Simple structure and easy maintenance
6. Actuator as Pneumatic/Electric or Manually Operated can be optioned.
