The main purpose of the anti wave valve is to discharge sewage or wastewater, and it can automatically close to prevent backflow of water from outside the ship. Anti wave valve, also known as storm valve, is designed for specific environments and applications. Its main function is to automatically shut down, thereby preventing backflow of water from the side of the ship. This type of valve is typically installed in ships or other water structures to protect internal systems from external waves or currents. The working principle and design of the anti wave valve enable it to respond quickly when needed, ensuring the stability and safety of ships or other water structures. ?
