PFA Lined बॉल चेक वाल्व: Features, Measurements & Materials

Prohibron9

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.

बॉल चेक वाल्व Features

  • Vertical installation & Horizontal Installation

    
for uncomplicated installation in all environments (min. 1 bar differential pressure required for horizontal installation).

  • Vertical Installation (up to 60°)

    
valve closes automatically due to center guided ball

  • Horizontal Installation (90° to 60°)

    
valve closes automatically, if backflow is 1,5 - 2,5m/s (water based)

  • Low Maintenance


    due to only a single moving part

  • Leakage Class D for Enhanced Process Safety

    
controlled and minimal leakage (<0,1% of valve capacity).
