Product Description

Product Description

Reliable Protection for Pumping Systems

The  Check Valve is designed to safeguard pipelines by preventing backflow and mitigating water hammer effects, ensuring smooth and secure operations in pumping stations, water supply networks, and industrial systems.

 

Key Features

1. Dual-Function Design
   • Backflow Prevention: Automatically closes to stop reverse flow when pump pressure drops.
   • Water Hammer Mitigation: Reduces surge pressure caused by sudden pump stops, protecting pipelines and equipment.
2. Robust Construction
   • Materials: QT500-7 (ductile iron), SUS304/316, SAF2205 (duplex), or bronze for corrosion resistance. ductile iron,duplex, or bronze
   • Seals: NBR/EPDM/HNBR options for compatibility with water, fuels, and chemicals.
3. Optimized Performance
   • Low Pressure Loss: Engineered for minimal head loss even at high flow rates (2 m/s).
   • Quick Response: Fast closure to prevent backflow and pressure surges.
4. Wide Application Range
   • Sizes: DN40-DN1200
   • Pressure Ratings: PN10/16/25/40, ANSI Class 150/300.
