1. Rapid Assembly: Socket Fusion Fittings utilize a hot-melt socket welding process. Welding is completed simply by inserting the pipe into the sleeve and heating for tens of seconds. The overall operation time is significantly shorter than the minutes or even hours required for traditional arc or gas welding. 2. Low O...

Conventional plastic piping (such as PPR and PVC) can be used stably for a long time below 90℃, but softening or even failure will...
View More1. Determine the Media Characteristics First, determine whether the medium being transported by the plastic pipe is water, oil, chemical solvents, or gas. Select materials based on its corrosiveness, viscosity, and temperature range. PPR is suitable for hot water, PVC for acid and alkali media, and PE-RT for low-temper...
View MoreWhat is Ball Valves PVDF?
1. Material Properties: PVDF (polyvinylidene fluoride) is a high-performance engineering plastic with excellent corrosion resistance, high-temperature resistance, and good mechanical strength. It can operate stably for extended periods in harsh media such as strong acids, strong alkalis, and organic solvents.
2. Simple Structure: The core of Ball Valves PVDF consists of a ball, seat, and stem. The ball rotates inside the valve body to open and close the valve. The sealing surface is made of PVDF material, enabling high-precision control with zero leakage.
3. Advantages Comparison: Compared to metal valves, PVDF ball valves are lighter, eliminate the risk of metal corrosion, and maintain extremely low particle release in high-purity fluid transportation (such as semiconductors and pharmaceuticals), meeting clean process requirements.
4. Applications: Widely used in fluid control systems in industries such as chemical, petroleum, pharmaceutical, environmental protection, biochemical, photovoltaic modules, and semiconductors, especially excelling in conditions requiring resistance to strong acids, alkalis, and high temperatures.
In which industries does Ball Valves PVDF play a key role?
1. Photovoltaics and Solar Energy: In the cleaning, cooling, and corrosion protection systems of photovoltaic modules, PVDF ball valves can withstand highly corrosive media such as hydrogen fluoride, ensuring long-term stable system operation.
2. Semiconductor Manufacturing: Semiconductor processes require extremely high fluid purity. The low particulate release and chemical resistance of PVDF valves make them the preferred valve body for the transportation of pure water, pickling solutions, and gases.
3. Chemical and Pharmaceutical Industries: Facing strong acids, strong alkalis, and organic solvents, PVDF ball valves provide reliable sealing performance, preventing leakage and cross-contamination, meeting GMP and environmental standards.
4. Environmental Protection and Biochemical Engineering: In wastewater treatment, sludge dewatering, and bioreactors, the corrosion resistance and high-temperature resistance of PVDF valves help systems maintain efficient operation in harsh environments.
5. Seawater/Aquariums: The high salinity and corrosiveness of seawater pose challenges to valve materials. The salt corrosion resistance of PVDF ball valves makes them widely used in seawater circulation and aquarium filtration systems.
