Overview of PVDF Ball Valves
A ball valve is a quarter-turn valve that uses a spherical ball with a bore to control fluid flow. PVDF ball valves are constructed using high-grade PVDF material, offering superior resistance to chemical attack and thermal stress.
Key Functions
- On/off flow control
- Isolation of pipeline sections
- Prevention of leakage
- Safe handling of corrosive fluids
PVDF ball valves are designed to deliver precise and reliable performance in critical applications.
Material Advantages of PVDF
PVDF is a fluoropolymer known for its exceptional physical and chemical properties.
Key Properties
- Density: ~1.78 g/cm³
- Tensile Strength: 40 – 55 MPa
- Operating Temperature Range: -40°C to +140°C
