Description

Characteristics & Advantages
| Feature | Benefit |
| All‑PPR construction | Zero metal ion release; ideal for deionised water, beverages, and sensitive processes. |
| Excellent chemical resistance | Immune to rust, scale, and most dilute acids/alkalis (except strong oxidisers). |
| One‑piece fusion welding | No threaded or flanged joints – eliminates potential leak paths. |
| Lightweight & insulation | Approx. 1/5 the weight of a stainless steel valve; electrically non‑conductive, no galvanic corrosion. |
| Low cost | Economical for mass production and large‑scale residential/light industrial projects. |

Applications


Comparison with Stainless Steel Ball Valves (304/316)
| Parameter | PPR Plastic Ball Valve | Stainless Steel Ball Valve (304/316) |
| Material (body & ball) | PPR | 304 / 316 stainless steel |
| Corrosion resistance | Excellent vs. acids, alkalis, salts; no rust | Moderate; susceptible to pitting in chlorides (especially 304) |
| Metal ion release | None | Traces of Cr, Ni, Fe, Mn |
| Temperature range | –20 °C to 70 °C (long‑term); peak 95 °C | –40 °C to 200 °C (depending on seat material) |
| Pressure rating | ≤ PN16 (1.6 MPa) | PN16 up to PN100 or higher |
| Connection method | Socket fusion (permanent, zero leakage) | Threaded, flanged, or welded (requires sealant/gaskets) |
| Weight (relative) | Very light (~1/5 of SS) | Heavy |
| Cost | Low | Medium to high (especially 316) |
| Maintainability | One‑piece – cannot be repaired; cut and re‑weld if damaged | Threaded/flanged types can be disassembled and replaced |
| Typical application | Domestic water, irrigation, mild chemicals | Oil, steam, high‑pressure gas, food processing (polished finish) |
