一、BJ41W夹套保温截止阀概述：

保温夹套截止阀是指关闭(阀瓣)由阀杆带动并沿阀座中心轴线做升降运动的阀门，在管路上主要用来接通或截断管路中的介质，BJ45流阻小,但不能做节流用。适用于化工、化肥行业的管路上，夹套内涵入蒸汽能防止介质结晶,及输送常温下会凝固的高粘度介质。

二、BJ41W夹套保温截止阀设计与制造标准：

●设计与制造：BS1873　、GB/T12235
●法兰尺寸：ANSI/ASME B16.5、JB/T79、GB9113
●压力温度：ANSI/ASME B16.34 、GB/T9131
●结构长度：ANSI/ASME B16.10　、GB/T12221
●对焊连接尺寸：ANSI/ASME B16.25 、GB/T12224
●检验与实验：API598、GB/T13927
