Cast iron flange bottom valve, also known as pump bottom valve, is a kind of energy-saving valves, generally installed in the pump underwater suction pipe at the bottom end of the pump to limit the pump pipe liquid back to the water source, playing a function of only in and out. The valve cover has many inlets and reinforcement played not easy to block, the main role is to be installed at the bottom of the pump to prevent the backflow of water.
Scope of Application
The bottom valve has reasonable design, advanced manufacturing technology, easy installation, use and maintenance. And has the advantages of small friction resistance, long service life, energy saving and so on. Widely used in petrochemical, chemical, textile, printing and dyeing, metallurgy, mining, irrigation and drainage industries such as water pump supporting facilities.
