China Check Valve factory

China Check Valve factory The Swing Check Valve has a flat disc that pivots or swings about a hinge pin. They are low cost, and have low head loss characteristics when fully open. But because of the long stroke and inertia of the disc, the traditional swing check valve may slam in vertical pipe installations. These valves are therefore sometimes outfitted with a lever and weight accessory. They can handle liquids with solids such as waste water.
