Product features

The pneumatic discharge ball valve is a special structure discharge valve. The valve seat is close to the end flange, with less material retention, compact structure, excellent sealing performance and other characteristics. It is commonly used in reaction pans in fine chemical, pharmaceutical and chemical industries, and can also be used to transport fine and soft particle media. The pneumatic discharge ball valve is made of PPL or M sealing material, which is more wear-resistant and temperature resistant. It is an ideal product for the toothpaste industry and the vacuum paste making pot.
Features of pneumatic discharge ball valve:
 
The pneumatic discharge ball valve can also be wrapped with FEP lining, and the internal flow channel and other parts are fully lined with FEP material, which can effectively isolate the erosion of the medium to the valve body. It has extremely high chemical stability, and can be used in the pipeline of corrosive gas, liquid and any other corrosive medium.
