Industrial Check Valves for Backflow Prevention

Valve Atlas stocks a complete range of check valves for preventing backflow in HVAC, plumbing, fire protection, and industrial piping systems. Check valves automatically close when flow reverses, protecting pumps, equipment, and piping from damage caused by reverse flow and water hammer.

Check Valve Types

Our inventory includes swing check valves, wafer check valves, spring-loaded check valves, ball check valves, and silent check valves. Available in cast iron, ductile iron, bronze, stainless steel, and carbon steel in sizes from 1/2 inch to 24 inch.

Fire Protection Check Valves

We carry UL Listed and FM Approved check valves for fire sprinkler system risers and fire pump discharge piping. These valves meet NFPA requirements and include options with alarm ports for fire department connections and inspector test connections.

HVAC and Plumbing Applications

Our check valves protect circulation pumps, booster pumps, and domestic water systems from reverse flow conditions. Silent check valves with spring-assisted closure prevent water hammer that can damage piping and equipment in high-rise buildings.
