Plastic butterfly valve, one of the butterfly valve family, has strong corrosion resistance, has a wide range of applications, is wear-resistant, easy to disassemble, protection and device are convenient and easy to operate, and its applicable fluids are: air, water, oil, chemical liquids. Its valve body structure adopts the center line type. It can be divided into worm gear type, handle type, electric type and pneumatic type according to different materials and application methods.

There are many kinds of connection methods between plastic butterfly valve and pipeline system. Different connection methods may change the fluid channel in the future, so it is very important to select the appropriate connection method. Generally including welding, bonding, electric smelting, rubber sealing, thread docking, flange docking and other methods, the detailed selection depends on the specific application of customers. In addition, different connection methods are used on one valve at the same time, which makes the valve structure and fluid passing method very different. Therefore, the customer should pay attention to the connection method and look out the small details when installing the device, so as to improve the structure and achieve the expected effect.

The installation and maintenance of plastic butterfly valve is very important, especially the maintenance. Not just the valve, the maintenance of many goods in our daily life is sometimes more important than any other aspects. Good maintenance methods can extend the service life of the items, improve the quality and improve the function. As for butterfly valve, users should check whether there are sundries on the sealing surface and butterfly valve channel regularly, and remove them in time, without leaving any dirt, so as to avoid affecting the application effect. At the same time, pay attention to the relationship between operating temperature and pressure. As operating temperature increases, its operating life should be shortened accordingly. Therefore, if we want to maintain an equal service life, we must reduce the application pressure.
