美国VETI/威迪品牌进口塑料双由令球阀采用浮动式结构，旋转杆带球体，独特的弹性唇式密封阀座，具有高密封性能和扭拒轻的功能。
进口塑料球阀UPVC性能特点
1、价格低,材料费用低，安装成本低，不同的工程比例不同；
2、材料轻,搬运、安装方便，节约时间及费用；
3、耐腐蚀；
4、耐老化,化学稳定性好；
5、管壁光洁,流体阻力小，无污染不滋生；
6、综合性能高,管件不传热，不导电，阻燃，机械强度高，适应性广。
进口塑料球阀CPVC性能特点
1、耐腐蚀性能强
CPVC管道无论是在酸，碱盐、氧化的环境中，暴露在空气中，埋于腐蚀性土壤里，在95°C的高温下，内外均不会被腐蚀，仍像当初安装一样坚固、可靠；
2、管道光洁
CPVC管道表面光洁，输送液体时具有较小的摩擦力，水垢亦不易生长和附着；
3、坚固耐压
CPVC比聚烯烃材料坚固，故所需卡箍、支架亦少。相同压力下，管道的管径比聚烯烃管小而达到同样流量，节省材料和安装时间：
4、良好的阻燃性
CPVC的限氧指数为60，管道不自然且不助燃，还具有限制烟雾的特性，不会产生有毒气体；
5、保温性能佳，热膨胀小
CPVC热传倒低，冬天可节省大部分保温材料及施工费用，也不会扭曲变形；
6、抗震性好
CPVC管道具有较好的弹性模量，抗震并能防止水锤效应；
7、耐老化性优异
CPVC管道具有优异的耐老化性的性能，使其正常使用时间比其它管道系统均有很大延长；
8、施工简易
CPVC管道比重小，连接方式与PVC相同，无需其他材料的配件。
