Product Description

Overview of pneumatic plastic butterfly valve
Pneumatic plastic butterfly valve has the advantages of strong corrosion resistance, wear resistance, light body weight, and a wide range of applications, valve body structure adopts the middle line type, easy to disassemble, simple maintenance, suitable for water, air, oil, corrosive chemical liquids. Pneumatic plastic butterfly valve can be directly adjusted by compressed air switching volume, assembly valve locator input 4-20mA signal, the medium flow, pressure, temperature and other parameters can be adjusted, is used in general pure water and raw drinking water piping system, drainage and sewage piping system, brine and seawater piping system, acid base and chemical solution system and other industries, The quality has been recognized by the majority of users.




Pneumatic plastic butterfly valve features
1, material health non-toxic, simple structure, small size, light weight, material consumption, small installation size;
2, the connection is made of two ends of the flange clamp, easy disassembly and maintenance, wear resistance, easy disassembly, simple and easy maintenance;
3, pneumatic UPVC butterfly valve switch quickly, 90 degrees reciprocating rotation, driving torque is small.
4, pneumatic plastic butterfly valve according to different media have a variety of materials, corrosion resistance, small size, suitable for a variety of pipelines, a wide range of applications.
