| Material | Features | Typical Applications |
|---|---|---|
| Carbon Steel (WCB) | Low cost, high strength, poor corrosion resistance | Water, steam, oil, natural gas at moderate temperatures |
| Stainless Steel (304/316) | Excellent corrosion resistance, good for high temp | Corrosive fluids, food industry, pharmaceuticals, chemicals, seawater |
| Cast Iron (Gray Iron, Ductile Iron) | Economical, suitable for low temp/pressure | HVAC systems, general water services |
| Brass/Bronze | Good corrosion resistance, easy to machine | Domestic plumbing, HVAC, small pipelines |
| Plastic (PVC, CPVC, PP, PVDF) | Lightweight, excellent corrosion resistance | Strong chemical fluids, low-pressure systems |
| Alloy Steel (e.g., Cr-Mo) | High temperature and pressure resistance | Power plants, petrochemical, refinery |
| Material | Features | Suitable Media |
|---|---|---|
| Stainless Steel Ball | Durable, corrosion-resistant | Most general-purpose fluids |
| Chrome-Plated / Hardened Ball | Wear-resistant | Frequent switching or abrasive media |
| PTFE (Teflon) Seat | Chemically resistant, up to ~200°C | Corrosive but moderate-temp media |
| PPL, PEEK, Metal Seats | Higher temperature and pressure resistance | High-temp, high-pressure, or abrasive media |
