氣動(dòng)PVC塑料蝶閥具有耐腐蝕性強(qiáng)，耐磨損，閥體重量輕等優(yōu)點(diǎn)，且應(yīng)用范圍廣，閥體結(jié)構(gòu)采用中線式，容易拆卸，維護(hù)簡單，適用于水、空氣、油類、腐蝕性化學(xué)液體。氣動(dòng)塑料蝶閥通過壓縮空氣即可直接進(jìn)行開關(guān)量調(diào)節(jié)，裝配上閥門定位器輸入4-20mA信號(hào)，可對(duì)介質(zhì)流量，壓力，溫度等參數(shù)進(jìn)行調(diào)節(jié)，被應(yīng)用于一般純水和生飲水的管路系統(tǒng)、排水和污水管路系統(tǒng)、鹽水和海水管路系統(tǒng)、酸堿和化學(xué)溶液系統(tǒng)等多個(gè)行業(yè)。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.
