Storm Valve[Search Related Products]
The principle of the marine storm valve is actually a one-way check. Generally, there is a tongue plate with a spring inside, which is closed under normal conditions, and the forward fluid can open the tongue plate. Open the valve, the reverse flow cannot open the tongue plate. Due to the limitation of the valve seat, there are also requirements during installation. First, it cannot be installed in reverse. Secondly, if the design requires vertical installation, it cannot be installed horizontally. Otherwise, it will be inconvenient to open or not to close tightly due to the weight of the inner tongue plate.
The storm valve is used to discharge sewage or waste water, and can automatically close and prevent the backside valve of the outboard water.
