Swing Check Valve
LD-818 Swing Check Valve

LD-818 (PP)

Swing Check Valve


  • Engineered for maximum flow, quick response and positive shutoff.
  • 100% full flow design.
  • Rapid closure helps to eliminate sudden back-flow water hammer.
  • Minimum back flow head pressure: 3 psi.
  • Swing check valves are designed for vertical and horizontal installations.
  • Fully serviceable, replaceable components for long life.
  • Extra heavy duty construction with glass reinforced polypropylene (GRPP) material for superior strength and excellent chemical resistance.

CAUTION: Valve must be installed with proper direction of flow. Do not install valve in upside down position. Swing check valves should be installed a minimum of 10 pipe diameters from a pump.
