Check valves are types of swing, lift, dual-plate, or stop-check variants, it allows fluid/gas flow in one direction only, preventing back flow. The self-actuating—opens with forward flow and closes under reverse flow, safeguards pumps, compressors, and piping from damage due to back flow or water hammer. 

Bada check valve are manufactured of brass, bronze, with seal way of metal-to-metal, resilient (EPDM, NBR), for zero leakage. It connects by threaded, welded with size ½ inch (DN15) to 48 inches (DN1200) or larger, depending on design. It works under pressure of Class 150 to Class 2500 (ANSI/ASME) or PN10 to PN400 (EN), temperature range from-196°C to +800°C (cryogenic to high-temperature applications).

Check valves are applied for use in Oil & Gas distribution, water/wastewater, HVAC, chemical/pharmaceutical, power plants, marine/shipbuilding
