一、不锈钢直通式衬氟截止阀产品简介：

手动、法兰连接、直通式、阀座密封面材料为氟塑料、公称压力 PN1.0-10.0MPa、阀体材料有铸钢、铸铁、不锈钢的截止阀。不锈钢直通式衬氟截止阀是指启闭件（阀瓣）由阀杆带动并沿阀座中心轴线做升降运动的阀门，是一种常用的截断阀，主要用来接通或截断管路中的介质，一般不用于调节流量。

二、不锈钢直通式衬氟截止阀结构特点：

1、  与闸阀相比，截止阀的结构较简单，制造与维修都较方便。

2、  密封面不易磨损、擦伤，密封性较好、寿命长。

3、  启闭时阀瓣行程较小，启闭时间较短、阀门高度较小。

4、  阀瓣与阀杆设计为一体结构，结构紧凑，使用安全。

5、  截止阀有三种结构形式：直通式、直流式、角式，其中直通式最为常用，角式可以安装在管路系统的拐角处，直流式流阻是截止阀中最小的。

6、  可根据用户需求配置气动、电动装置，满足遥控和程控的需要。

7、  更换零件衬里材料可适用各种介质。
