是说介质的流向不受限制5、形体结构比较简单，制造工艺性较好6、结构长度比较短。闸阀缺点：1、闸阀的外形尺寸和开启高度较大，所以在安装的时候所需要的空间亦较大2、开启和关闭时间会比较长。3、在启闭过程中，密封面人相对摩擦，摩损较大，甚至要在高温时容易引起擦伤现象4、一般闸阀都有两个密封面，给加工、研磨和维修增加了一些困难一般，闸阀不可作为调节流量使用。它可以适用低温压也可以适用于高温高压，并可根据阀门的不同材质。但闸阀一般不用于输送泥浆等介质的管路中气动截止阀的基础知识气动截止阀的基础知识说白了也就是在气动阀门的位置上设置一个手动操作机构，从而大大提高了，运行系统的安全可靠性，也增加了气动阀门在失去控制后的变应能力。气动截止阀的特点是由手动机
