Plastic Solenoid Valves (Yongchuang YCWS10-01) | Residential plumbing, RO systems, irrigation | - Plastic body (Polypropylene/ABS, ISO 9001 certified) - Medium pressure: 5 bar (▲1 bar over typical 4 bar plastic valves) - 24V DC (IEC 60947) - CE certified (EMC 2014/30/EU) | - Lightweight (30% lighter than metal valves) ▲ - Corrosion-resistant (pH 5-9 water) ▲ - Cost-effective (20% cheaper than metal) ▲ | - Limited to ≤5 bar pressure ▼ - Not for aggressive chemicals ▼ |
Metal Solenoid Valves | Industrial systems, high-pressure apps | - Metal body (brass/aluminum, ASTM B221) - High pressure: 10 bar (ISO 10734) - 24V DC (IEC 60947) - Often CE/FCC certified | - Durable for harsh environments ▲ - Handles up to 10 bar pressure ▲ - Longer lifespan ▲ | - Heavier (requires robust mounting) ▼ - Prone to corrosion without coatings ▼ - Higher cost ▼ |
Diaphragm Valves | Chemical/pharma, food industries | - Flexible diaphragm (EPDM/Santoprene, ASTM D2000) - Full-seal design (ISO 5208) - CE certified | - No dead space (easy cleaning) ▲ - Sanitary design (FDA-compliant) ▲ - Resists chemical corrosion ▲ | - Max 6 bar pressure ▼ - Diaphragm wear over time ▼ - Limited to specific media ▼ |
Ball Valves | Gas pipelines, HVAC systems | - Quarter-turn operation (ISO 5211) - Full bore (minimal pressure drop) - ASTM A182 materials | - Quick shut-off (within 3 seconds) ▲ - Low maintenance (few moving parts) ▲ - Durable for frequent use ▲ | - Not for slurry/viscous fluids ▼ - Higher cost than gate valves ▼ - Requires precise alignment ▼ |
Check Valves | Plumbing, HVAC, fire protection | - Spring-loaded/gravity actuated (ASME B16.34) - Full port design - CE/FDA certified | - Automatic backflow prevention ▲ - No external power needed ▲ - Simple installation ▲ | - Causes 10-15% pressure drop ▼ - Fails at low flow (<0.5 L/min) ▼ - Direction-specific ▼ |
Gate Valves | Pipeline systems, oil/gas industries | - Linear closure (ISO 5752) - Full port (no pressure drop) - ASTM A105 materials | - Minimal flow resistance (0% pressure drop) ▲ - Handles up to 15 bar ▲ - Long lifespan ▲ | - Slow operation (needs full rotation) ▼ - Not for throttling ▼ - Prone to leakage if misaligned ▼ |
