涡轮塑料蝶阀 D371X-10S涡轮PVC对夹式蝶阀

D371X-10S对夹式PVC涡轮塑料蝶阀描述对比：

手柄蝶阀手柄杆直接传动阀片，开关迅速．但费力．

D371X-10S对夹式PVC涡轮塑料通过涡轮传动阀片，开关慢但省力．所以管内压力大时手柄蝶阀特别费力．

工程中常用的蝶阀一般是D371X-10S对夹式PVC涡轮塑料，因为除了省力外，它的密封好于手柄蝶阀，特别开关频率高的环境下，使用寿命高于手柄蝶阀．劳动强度小 。D371X-10S对夹式PVC涡轮塑料适用范围：阀体重量轻、耐腐蚀性强，例如：纯水和生饮水的管路系统、排水和污水管路系统、盐水和海水管路系统、酸碱和化学溶液系统等多个行业等行业。D371X-10S对夹式PVC涡轮塑料突出特性：设计先进、开关扭矩小、密封性能强。D371X-10S对夹式PVC涡轮塑料产品绿色环保，很好的耐酸碱、耐腐蚀性能。具有抗冲刷、不接疤、重量轻、易装卸、好维护、寿命长等优势，是取代金属蝶阀的**。
