Product Details

Product overview
The principle of marine wave valve is actually one-way check, generally inside is a tongue disc with a spring, which is closed at normal times, and the forward fluid can open the tongue disc. Open the valve, the reverse fluid cannot open the tongue disc. Due to the limitation of the valve seat, there are also requirements during installation, not reversed, and secondly, if the design needs to be installed vertically, it cannot be installed horizontally. Otherwise, it will be affected by the weight of the tongue disc inside and it will be inconvenient to open or not closed tightly. Wave valves are used to discharge sewage or wastewater and automatically close and prevent outboard water from flooding.
