This 32 mm Swing Check Valve (Slip x Slip, Solvent Weld) prevents backflow in PVC pressure pipe systems, protecting pumps, tanks, and equipment from reverse flow. The swing-disc mechanism opens with forward flow and closes automatically under back pressure. Manufactured from rigid PVC for corrosion-free service in irrigation, water supply, and chemical handling applications. Solvent-weld sockets on both ends ensure a permanent, leak-free installation.
