Reliable Non-Return Protection for Corrosive Media Handling

The Prohibron9 Ball Check Valve offers secure, maintenance-friendly backflow protection for pipelines transporting corrosive, pure, or vaporous media. Engineered with a virgin PFA lining, it provides superior chemical resistance, minimal permeation, and vacuum-tight sealing. Its pressure-resistant metal body ensures durability in high-pressure systems, while the valve’s center-guided ball design allows automatic closing in both vertical and horizontal installations (with defined minimum flow conditions).

With only one moving part and no need for external actuation, the Prohibron9 delivers long service life with minimal maintenance. Optional non-stick linings and custom coatings further enhance adaptability, making it the optimal solution where safety, cleanliness, and reliability are essential. The Prohibron9 stands as a key component in aggressive media systems where conventional materials like stainless steel or plastics fall short.

Proven Performance

Industry Applications

PFA-lined components are essential in industries that handle aggressive or high-purity fluids. Thanks to PFA’s exceptional chemical resistance, the Prohibron9 can be used with strong acids, bases, solvents, and even permeating agents without degrading. Its high thermal stability, non-stick surface, and low permeability enable safe and efficient operation even in high-temperature and pressure conditions, reducing product contamination and material wear.

These properties make PFA-lined ball check valves especially suitable for industries where fluid purity, corrosion resistance, and low maintenance are vital. From chemical plants to pharmaceutical production, the Prohibron9 ensures reliable backflow prevention under chemically and mechanically demanding conditions.
