Use the self-closing diaphragm check valves to protect against hazardous and corrosive reverse flow. The diaphragm reseats against the seal without relying on gravity, mounting position, or reverse flow, ensuring reliable sealing even at low pressures. A union nut allows easy inspection and removal with minimal piping disruption. No loose or sliding internal parts eliminate chattering and help keep operation quiet. As inlet flow passes through the valve, both the diaphragm and valve seat are kept clean by the flushing action, keeping the sealing area clean and free of particles, minimizing the risk of leakage.
