The Stainless steel screwed swing check valve is an automatic non-return valve used to prevent backflow in pipelines. It features a hinged "swing" disc that opens with forward pressure and closes via gravity or reverse flow. Crafted from SS316/SS304, it is highly resistant to corrosion. The screwed (NPT/BSP) ends facilitate easy installation in compact systems. It is best suited for horizontal flow in low-velocity water, oil, and gas applications where minimal pressure drop is required
