Product features

Pneumatic discharge ball valve is a kind of discharge valve with special structure. The valve seat is close to the end face flange, with less material retention. It has the characteristics of compact structure and superior sealing performance. It is commonly used in reaction pots of fine chemical industry, pharmaceutical industry and chemical industry, and can also be used for conveying fine and soft particles. The pneumatic discharge ball valve adopts ppl or m sealing material, which is more wear-resistant and temperature resistant. It is an ideal product for toothpaste industry and vacuum paste making pot.
Features of pneumatic discharge ball valve:
 
The pneumatic discharge ball valve can also be lined with FEP. The internal flow channel and other parts are wrapped with FEP material, which can effectively isolate the corrosion of medium on the valve body, and has high chemical stability. It can be applied to the pipeline of corrosive gas, liquid and any other corrosive medium.
