一、BJ41W夾套保溫截止閥概述：
保溫夾套截止閥是指關閉(閥瓣)由閥桿帶動并沿閥座中心軸線做升降運動的閥門，在管路上主要用來接通或截斷管路中的介質，BJ45流阻小,但不能做節流用。適用于化工、化肥行業的管路上，夾套內涵入蒸汽能防止介質結晶,及輸送常溫下會凝固的高粘度介質。
二、BJ41W夾套保溫截止閥設計與制造標準：
●設計與制造：BS1873 、GB/T12235
●法蘭尺寸：ANSI/ASME B16.5、JB/T79、GB9113
●壓力溫度：ANSI/ASME B16.34 、GB/T9131
●結構長度：ANSI/ASME B16.10 、GB/T12221
●對焊連接尺寸：ANSI/ASME B16.25 、GB/T12224
●檢驗與實驗：API598、GB/T13927
