Check valves for agricultural irrigation pump stations and mainline systems. Check valves prevent backflow in pump discharge lines, protecting your pump from water hammer and reverse rotation when the system shuts down — a critical component for any centrifugal pump installation.

  • Swing check valves and spring-loaded check valves for pump discharge and mainline applications
  • Select by pipe size and connection type to match your pump outlet and mainline fittings
  • Flanged and threaded configurations available for pump station and inline installations
