DN200 Ductile Iron Flanged Gate Valve with 18 Month Warranty and Low Flow Resistance for Industrial Applications
The DN200 Ductile Iron Flanged Gate Valve is engineered for medium pressure applications with exceptional flow efficiency and reliable performance. Featuring a straight-through design for minimal flow resistance and bidirectional operation capability.
- Small flow resistance - Straight medium channel allows direct flow with minimal pressure drop
- Effort-saving operation - Gate movement perpendicular to flow direction reduces operating torque
- Large height design - Extended opening/closing stroke with screw-driven descent mechanism
- Reduced water hammer risk - Gradual closing action minimizes hydraulic shock effects
- Bidirectional flow capability - Symmetrical gate design supports medium flow in both directions
