How Swing Check Valves Work

PVC swing check valves use a hinged flap (disc) that opens with forward flow and automatically closes to stop reverse flow. This simple yet effective design makes them essential for protecting piping systems from backflow that can damage equipment or contaminate water. Theystand apart with precision engineering, durable check valve construction that resists pipe corrosion, and a wide range of compatible system components.

Key Benefits of NDS Swing Check Valves

Choosing an NDS swing check valve provides confidence in performance and long-term value. Some of the key benefits include:

  • Backflow prevention– safeguards systems from reverse flow and contamination.
  • Durability– made from high-quality, corrosion-resistant PVC pipe.
  • Low maintenance– minimal moving parts and easy access for inspection.
  • Compatibility– fits seamlessly into standard piping systems, including IPS S x S connections.
  • Cost-effectiveness– reduces the risk of downtime, repairs, and property damage while maintaining consistent water pressure.

Typical Applications

NDS swing check valves are highly versatile, making them suitable for multiple environments:

  • Residential irrigation systems– protecting potable water lines.
  • Stormwater drainage and sump pump discharge lines– ensuring proper flow direction.
  • Commercial and municipal water systems– meeting safety and compliance needs.
  • Pools, spas, and fountains– preventing backflow for efficient water circulation.

Installation Tips

For optimal performance, be sure to follow these best practices:

  • Install with the flow arrow pointing in the desired direction of flow.
  • Support piping to minimize stress on the valve.
  • Ensure the flap moves freely before the pressurized system.
  • Inspect periodically for debris or buildup that could affect performance.

By following these guidelines, you’ll extend the life of the valve and maintain consistent system efficiency.
