Check Valve

Check Valves

Direct water flow one-way through pipe with check valves. Check valves are one-way valves installed in pipe systems to prevent the backflow of water and protect the pipe and other system components from costly damage.

Key Features

  • Water flows one-way through check valves when the water pressure triggers the internal spring or flap to open
  • NDS offers 1/2 in. – 2 in. spring check valves, 3/4 in. – 4 in. swing check valves, as well as sump pump and foot valves
  • Spring check valves allow water through when the water pressure is greater than the weight of the spring
  • Swing check valves allow water through when the flap opens; flap shuts to prevent backflow if water direction changes
  • Check valves are made of polyvinyl chloride (PVC)

Applications

  • Directs water flow one-way through pipe and allows water through; prevents backflow and avoids costly property damage, pipe corrosion, and system issues

  • Use for subsurface irrigation or in sprinkler control system installation; works with most PVC pipe to transport water and prevent backflow in pressurized systems

  • Adjustable inline, true union, and compact spring check valves; low-profile, compression, true union, and sump pump swing check valves connect pipes and other system components to allow water to flow through and prevent backflow

Installation & Maintenance

  • Valve has ends that connect to pipe; ends can be turned to tighten onto pipe or may require solvent cement to keep in place

  • Valve can vibrate or emit noises to indicate damage; replace as needed

Materials & Sustainability

  • Check valves are made of polyvinyl chloride (PVC)

  • Onsite flow management protects pipe systems from backflow which can lead to corrosion of pipes, property damage, and issues with the flow system
