S&W Single Plate Valve

The S&W Single Plate Valve—also known as a single disc or wafer-type check valve—is a compact, lightweight backflow prevention valve designed for horizontal or vertical installations. It features a single swing-type disc that opens with forward flow and automatically closes to prevent reverse flow. Ideal for water treatment, HVAC, steam systems, and industrial piping, it offers low-pressure drop and easy installation between flanges.
