Nhà Sản Xuất : Neles                                                 Neldisc high performance triple eccentric disc valves, series L9B/L90B, weld end                                              The L9B/L90B-series valve is a high performance triple eccentric disc valve. The body is fabricated of boiler vessel quality carbon steel, and can easily be welded into the piping without preheating. As a result of the unique geometry, contact between the disc and seat is mechanically induced, and does not rely on assistance from differential pressure. The L9B/L90B-series seating principle is based on the same ingenious design applied in over 300 000 other Neldisc® valves already delivered.
