Product features

Pneumatic UPVC plastic butterfly valve has the advantages of strong corrosion resistance, wear resistance, light weight of valve body, etc., and has a wide range of applications. The valve body structure adopts a central line type, which is easy to disassemble, simple to maintain, and suitable for water, air, oil, and corrosive chemical liquids. The pneumatic plastic butterfly valve can directly adjust the on-off value through compressed air. The 4-20mA signal input from the valve positioner can adjust the medium flow, pressure, temperature and other parameters. It is used in many industries, such as pipeline systems for general pure water and raw drinking water, drainage and sewage pipeline systems, brine and seawater pipeline systems, acid and alkali and chemical solution systems, The quality has been recognized by the majority of users.
