FRP pipes and valves have been widely used due to its better chemical resistance than other materials. General stainless steel valves cannot be used under the condition of high temperature hydrochloric acid and acid alkali alternation. The price of FRP valves is only about 1/3 of that of stainless steel valves of the same size.

When the pneumatic butterfly valve fails, please do not panic. First, calm down to find out the cause of the pneumatic butterfly valve failure, and then find out the solution!
The pneumatic butterfly valve shall be comprehensively considered in many aspects, including the influence of the pressure of the pipeline system on the pneumatic butterfly valve, the pressure that the butterfly plate can withstand when it is closed, and the working temperature that the elastic valve seat can withstand under high temperature. The length and overall height of the pneumatic butterfly valve are relatively small, with very good flow performance. When the pneumatic butterfly valve is used to control the flow, it is necessary to carefully select the type and size of the butterfly valve, so as to ensure that the pneumatic butterfly valve can give full play to its advantages to work.
