Your #1 Foot Valve Manufacturer in China
- The foot valve is a one-way valve, usually installed at the bottom of the pump suction pipe or under the water storage container, through the automatic opening and closing of the valve flap to prevent liquid backflow, to ensure that the medium in the pipeline “only in”, to maintain the stable operation of the system and reduce the water hammer effect.
- The structure includes a valve body, valve disc, and spring, which drives the valve disc open by fluid pressure, and fast closing by spring force effectively avoids the media backflow and impurities into. Mainly used in petrochemical, water conservancy, chemical and other fields, with energy-saving characteristics and low maintenance requirements, especially suitable for pumping pipes and liquid transportation systems.
