The main purpose of the wave valve is to discharge sewage or waste water, and can be automatically closed to prevent outboard water backflooding. Storm valves, also known as storm valves, are designed for use in specific environments and applications. Its main function is to be able to automatically close, so as to prevent outboard water backpouring. Such valves are usually installed in boats or other above-water structures to protect internal systems from external waves or currents. The operating principle and design of the wave valve enable it to respond quickly when needed, ensuring the stability and safety of a ship or other above-water structure.
