Series | Code | Description |
BWL | BW150 | NELES BWL-SERIES, METAL SEATED DOUBLE ECCENTRIC VALVE, RATING ASME 150 (BWL_C) |
The Type BWL_C refers for high temperature. The values for the standard valve are based on single U-shape seat construction and for standard materials. The material as well as the seat selection has an effect on valve dimensions and Nelprof sizing due to strength calculations. The valve is designed for control and on/off purposes. Temperature range start from -50 ... 475 °C, pressure rating ANSI class150, PN25. Use Nelprof code BWL_C for Double Flanged,Wafer, Lug and Butt Weld End design sizing.
