ZHENGFENG VALVES Cast steel ball valve is divided into: floating ball valve and trunnion mounted ball valve.  

Our company are usually used PTFE、RPTFE、PPL、DEVLON and metal as seat sealing ring materials in the production. 

Therefore, in the selection of the structure and performance of the ball valve, the working temperature and fire prevention of the ball valve should be considered, especially in the departments of petroleum.
