2. Plastic pipe caps fitted on steel pipes, which can be installed at any position on the pipeline under normal circumstances for ease of operation and inspection. Pay attention to the sealing property of the plastic pipe caps to prevent leaks and affect normal operation.

3. Ball valves, stop valves, and gate valves equipped with plastic pipe plugs can only be fully open or fully closed; they are not to be used for flow regulation to prevent erosion of the sealing surfaces and accelerated wear. Gate valves and upper threaded stop valves are equipped with reverse-sealing devices. By turning the handwheel to the upper position and tightening it, leakage of the packing medium can be prevented.

4. Use the handwheel to plug the plastic tube. Do not rely on levers or other objects to prevent damage to valve parts. The handwheel is closed when turned clockwise, and open otherwise.
