Foot valve is a kind of energy-saving valve, usually installed at the bottom of pump suction pipe, to prevent medium in the pipe flow back to water source. There are many inlet holes and reinforcing ribs in the valve cover, so the pipe will not be easily clogged up.
Features:
DN : DN15~DN400
PN:2.5~25bar
