The use of PE pipes in the current pipe market is becoming increasingly widespread.As we all know,the strength of PE pipe hot melt or electric melt joints is higher than that of the pipe body,and the joints will not break due to soil movement or live load.PE pipes require various professional operations during installation and construction.Today,PE pipe manufacturers will introduce the connection method of PE pipe valves.
1.Flange valve
Because the flange valve already comes with a flange on the valve body,it only needs to be installed with a support ring and corresponding specifications of flange plates on the PE pipe.The support ring needs to be hot-melt connected,and the flange plate needs to be bolted to the flange valve;
2.Screw valve
Screw valves are usually made of outer threads,so you need to install an inner thread directly on the pipeline.The inner thread is directly connected to the PE pipe by hot melting,and then connected to the screw valve screw;

3.Copper gate valve
Copper gate valves are generally connected by flanges,using the same method as"flange valves".If encountering gate valves with internal threads(usually small pipe diameters),external threads should be installed directly on the pipeline,using the same installation method as"screw valves".
PE pipes are widely used in various fields due to their high strength,corrosion resistance,non toxicity,and wear resistance,and have great development prospects in the market.Through the above introduction,we have also gained some understanding of the connection method of valves for PE pipes.If you have any further questions,please feel free to call us for consultation.
