气动PVC塑料蝶阀具有耐腐蚀性强,耐磨损,阀体重量轻等优点,且应用范围广,阀体结构采用中线式,容易拆卸,维护简单,适用于水、空气、油类、腐蚀性化学液体。气动塑料蝶阀通过压缩空气即可直接进行开关量调节,装配上阀门定位器输入4-20mA信号,可对介质流量,压力,温度等参数进行调节,被应用于一般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。Pneumatic UPVC plastic butterfly valves have advantages such as strong corrosion resistance, wear resistance, and light weight, and have a wide range of applications. The valve body structure adopts a centerline type, which is easy to disassemble and maintain. They are suitable for water, air, oil, and corrosive chemical liquids. The pneumatic plastic butterfly valve can directly adjust the on-off value through compressed air. Equipped with a valve positioner to input 4-20mA signals, it can adjust parameters such as medium flow rate, pressure, temperature, etc. It is applied to various industries such as general pure water and raw water pipeline systems, drainage and sewage pipeline systems, saline and seawater pipeline systems, acid alkali and chemical solution systems, etc.
