1. Parallel Double Disc Cast Steel Gate Valve adopts two parallel gate discs with wedge expanding mechanism. When closed, the wedge pushes the two gate discs against the seats on both sides to achieve sealing.
2. The valve is designed in compliance with API 6D standard, suitable for process pipelines of steam, water and oil products.
3. Materials for valve body and gate disc assembly can be selected according to temperature and medium conditions.
4. Widely used in power station, metallurgy and chemical pipelines for full open / full shut medium isolation. Throttling service is prohibited.
1. Parallel double disc with wedge expanding structure. It can automatically compensate the wear of sealing surfaces during closing to maintain stable sealing performance.
2. Hard alloy is hardfaced on sealing surfaces of gate disc and seat, featuring high temperature resistance, wear resistance and erosion resistance.
3. The gate discs retract mutually when opening, separating the sealing surfaces to reduce friction and wear during operation.
4. Bottom-installed blowout-proof stem to ensure safe equipment operation.
5. Full bore flow passage with low resistance to medium flow.
6. Easy maintenance and disassembly; the gate disc assembly can be inspected and replaced.
