Stainless Steel Check Valve
Product Details：Check valves are generally used to protect pumps or similar equipment, allowing the flow only in one direction and preventing flow reversal due to back pressure. The swing type check valves are designed to produce a low pressure drop in the pipeline. This design provides a tight seal as well as a fast reaction to the closure. Check valves are mainly used in the application of water, steam, oil, crude petroleum and petroleum products, and other nonaggressive fluids.Applicable StandardDesign Standard: BS 1868Face to Face: ASME B16.10End Flange: ASME B16.5, ASME B16.47 Butt welding Ends: ASME B16.25 Inspection and Test: API 598Products RangeSize: 2" ~ 36" (DN50 ~ DN900)Rating: ANSI 150lb-2500lb Body Materials: CF3, CF8, CF3M, CF8M, A890 4A, A890 5A, CN7M, Monel etc.Design FeaturesStandard port or Full portBolted cover.Swing type disc designThreaded or welded seatFlanged or butt welding ends Optional dashpot device
