What Is a Foot Valve?

The bottom valve, also known as a check valve, is a low-pressure flat valve. Its role is to ensure that the liquid flows unidirectionally in the suction pipeline to make the pump work normally. When the pump stops intermittently for a short period of time, the liquid cannot return to the water source tank. The suction pipe is filled with liquid to facilitate the start of the pump. [1]

The bottom valve is a kind of energy-saving valve. It is generally installed at the bottom end of the underwater suction pipe of the pump to restrict the liquid in the pump pipe from returning to the water source. There are many water inlets and reinforcing ribs on the bonnet, which are not easy to block, and are mainly used in pumping pipelines. The role of watercourses and supports. Calibers are single, double and multi-lobed, flanged and threaded.

The bottom valve is welded to the bottom of the container, so as to achieve the best effect of emptying, cleaning and disinfection. In addition, the working medium can be well mixed according to various process requirements during operation.
