Product Description

Our swing-type cast iron wire check valve is connected to the pipeline through a threaded connection, that is, the internal or external threads at both ends of the valve are screwed together with the corresponding external or internal threads on the pipeline to achieve a tight installation of the valve and the pipeline. This connection method is easy to operate and does not require complex welding processes or large installation tools. Only an ordinary wrench is required to complete installation and disassembly. It is widely used in building water supply and drainage, small industrial pipelines and other fields. It is an important component to ensure the one-way flow and stable operation of the pipeline system medium.
