🔎 What It Is:
A Single Wafer Check Valve is a compact, lightweight valve designed to prevent backflow in a piping system. It consists of a single disc or plate that swings open to allow flow in one direction and closes against a seat to block reverse flow. The wafer design allows it to fit snugly between two pipe flanges, minimizing space requirements.
