PPR Ball Valve: Technical Specifications and Features

Descripción general del producto

PPR ball valves are high-performance flow control devices designed specifically for polypropylene piping systems. These valves combine the durability of PPR material with the reliable operation of a ball valve mechanism, creating an ideal solution for both residential and industrial applications. The unique design integrates a brass or stainless steel ball with PPR body components, offering superior corrosion resistance while maintaining excellent sealing performance.

Composición del material

The valve body is constructed from high-quality polypropylene random copolymer (PPR), ensuring chemical resistance and long-term durability. The ball component typically consists of chrome-plated brass or stainless steel for smooth operation and reliable sealing. Stem seals are made from PTFE or EPDM, providing excellent wear resistance and leak-proof performance. All materials comply with drinking water standards (NSF/ANSI 61) and are lead-free.

Instrucciones de instalación

1. System Preparation: Ensure piping is properly aligned and supported

2. Soldadura por fusión: Use standard PPR welding equipment at 260°C (±5°C)

3. Conexiones roscadas: Apply appropriate sealant (Teflon tape for metal threads)

4. Orientation: Install with stem axis vertical or horizontal (avoid 45° positions)

5. Operation Check: Verify smooth operation before system pressurization

6. Prueba de presión: Conduct hydrostatic test at 1.5× working pressure

Seguro de calidad

Each valve undergoes rigorous testing including:

• Hydrostatic shell test at 2.4×PN for 1 minute
