一、PQ940F电动偏心半球阀特点：
1、解决了工业生产中的浆状、混流液体、灰尘等介质在管道输送中沉淀、易结垢、阻塞，使阀门关不严等问题。
2、开关轻便，开启时球与壳体脱离，无任何接触，启动扭矩小，转动灵活。关闭时，半球与阀座的挤切作用能除去密封面上的污物，使阀门顺利启闭，安全系数高，密封性能好。
3、密封面的偏心结构，使球面能自动补偿磨损，能保持阀门的密封，使用寿命长。
4、该阀门T型是属于耐磨硬密封球阀，它的密封副材料是特殊的，密封面要经过特殊耐磨处理。处理后表面达到HRC65-72度，故阀门的耐磨性能特别好。
5、阀门表面油漆，有常温和高温两种。高温用耐温600℃的进口漆，喷涂后，高温使用不烧漆、炭化、焦化现象。不变色。
