Connection between PE pipe and valve: flanged valve, because the flanged valve has its own flange on the valve body, it only needs to add a support ring and a flange of corresponding specifications to the PE pipe, and it can be installed. The support ring needs hot-melt connection, and the flange sheet is connected with the flange valve bolts; screw valve, screw valve is generally an outer wire, so it is necessary to install an inner wire directly on the pipeline, and the inner wire is directly connected to the PE pipe by hot-melt connection, and then Screw connection with screw valve; copper gate valve, copper gate valve is generally flange connection, the method is the same as "flange valve", if you encounter a gate valve with inner wire (usually small diameter), then install the outer wire directly on the pipeline. , the installation method is the same as the "screw valve".
