                              j41h截止阀通常又分为j41h美标截止阀和j41h国标截止阀,那其使用范围呢
                               j41h国标截止阀的使用范围



                                j41h国标截止阀一般不用来做调节流量之用,因为其只适用于全关和全开,若是定制的话,也能做到调节和节流。密封面堆焊Co基硬质合金,所以耐腐、抗摩擦性好、耐磨,能够用于腐蚀性介质,当然也能用于水、气、油等介质。

                              j41h美标截止阀的连接形式是法兰连接,结构形式是阀瓣非平衡式直通流道,阀门密封面材质是Cr13不锈钢。j41h美标截止阀密封面间的摩擦力小,所以经久耐用,适用于中低
