Stainless Steel Check Valve NRC-W for Efficient PP Pipe Welding

Spring check valve under welding with PP pipes consists of a stainless steel check valve, two flange bolls with flanges, bolts, nuts and is designed for installation in polypropylene pipelines to prevent reverse flow. Mounting is carried out by means of diffusion welding, which greatly simplifies installation in comparison with other methods: flanged, interflanged or under welding with steel pipes..DN:110,125,160 SDR 11, 160 SDR 7.4, 160 SDR 9, 200 SDR 11, 200 SDR 7.4, 200 SDR 9, 63, 75, 90
