Foot Check Valve is a low pressure flat valve.It is used to ensure one-way flow of liquid in the suction line of a pump. When the pump stops running, the valve of the foot valve closes to prevent the liquid from flowing back into the water source. It is usually used in conjunction with a filter to prevent impurities from entering the system.
The foot valve is composed of a valve body, a valve disc, a valve cover, a sealing ring, a gasket and other components. The foot valve is sealed and opened through the elastic action of materials such as springs or rubber.
1. The foot check valve is designed for the equipment of the pumping station. When the pumping stops, the disc can quickly closed by the spring pressure before any over pressure occurs due to the return flow.
2. Reasonable design, can effectively avoid turbulence;
3. Easy to install, maintenance and replacement FBE coating inside and outside.
4. It is widely used in pumping stations and networks for clean water distribution, irrigation and water treatment.
5. All current international standard interfaces can be provided, such as: welded type, clamp type, threaded type, etc.
