Check Valves

In almost every piping system, there is a need for backflow prevention. Most piping systems utilize pumps or compressors to generate needed pressure for movement of line fluids or gases. When rotating equipment stops, flow reversal or backflow occurs. Check valves are used to stop backflow and protect rotating equipment or other mechanical devices from the sudden backflow surges that may occur. To satisfy your needs, specify CRANE Energy Flow Solutions®' Check Valves — the worldwide leader of valves manufactured for the prevention of backflow.
