说明:1、低温法兰截止阀,150磅级和300磅级结构长度相同(企业标准) 2、LF2制造的非长颈低温阀,其阀门型号中低温长度代号“D”省略;低温级别代号“无”。例如:J61Y-40F
Notes:1.The face to face of low temperature flange globe valve,class 150 is ame as class 300 (enterprise standard) 2.The code”D” of low temperature type of LF2 produced non-long neck low temperature valve is default,code of low temperature is “none”,for example J61Y-40F |
