PPSU Ball
At INDIANO, we have redefined valve performance with our Advanced Engineered Polymer PPSU Ball – a breakthrough innovation designed to solve one of the most common problems in plumbing systems: valve jamming due to hard water (high TDS).
Unlike traditional brass balls that suffer from scaling, corrosion, and eventual leakage, our PPSU (Polyphenylsulfone) ball offers unmatched durability, chemical resistance, and smooth operation – even after long periods of non-use.
Understanding the Problem
In most areas of our country, ground water contains high levels of TDS (Total Dissolved Solids).
When hard water passes through a valve with a CP brass ball, a chemical reaction between negative ions in water and positive ions in the brass causes limescale formation.
Over time, this leads to valve jamming, increased operating difficulty, and costly replacements.
The INDIANO Solution – “PPSU Ball”
Our research and engineering expertise have led us to the perfect solution – the PPSU (Polyphenylsulfone) Ball.
- Neutral in reaction – Does not attract or react with ions in hard water.
- No Effect of Hard Water – 100% resistant to limescale and mineral deposits.
- Anti-Jamming – Works smoothly even after long periods of non-operation.
- Why PPSU Ball?
- No Effect of Hard Water: 100% resistant to limescale and mineral deposits.
- Corrosion Resistance: Unaffected by water, humidity, or harsh environments.
- Ultra-High Toughness: Withstands high pressures without deformation.
- High Heat Resistance: Performs reliably up to 200°C, making it ideal for hot water applications.
- Hydrolytic Stability: Maintains mechanical strength and shape over years of water exposure.
- Stress Crack Resistance: Prevents cracks under thermal and mechanical stress.
- High Notched Impact Toughness: Superior resistance to sudden force or pressure surges.
- The INDIANO Advantage
By integrating PPSU Ball technology into our Top Entry Ball Valves and Concealed Ball Valves, we deliver products that are engineered for Indian water conditions, ensuring performance that lasts longer, operates smoother, and saves money in the long run.
