A PPR (Polypropylene Random Copolymer) ball valve is a critical component in modern plumbing, specifically designed for use with PPR piping systems. Unlike metal valves that thread or solder on, these are typically joined using heat fusion, creating a leak-proof, monolithic bond.
Key Features
Corrosion Resistance: Unlike brass or steel, PPR won't rust or corrode, making it ideal for hard water areas.
Temperature Tolerance: It handles both cold and hot water applications (up to about 95°C, depending on pressure).
Full Port Design: Most PPR ball valves offer a "full port," meaning the internal diameter of the ball matches the pipe size, ensuring minimal pressure drop.
Chemical Neutrality: It doesn't react with most chemicals and won't affect the taste or odor of drinking water.
Technical Specifications
Commonly, these valves are rated by their PN (Pressure Nominal) value:
