H42X Lifting Foot Valve

H42X Lifting Foot Valve Structure
H42X Lifting Foot Valve Structure

The H42X lifting bottom valve is installed at the bottom of the suction pipe of the pump and can automatically prevent the fluid from flowing backward. This valve is a kind of energy-saving valve. It restricts the liquid in the pump pipe from returning to the water source. It can only enter and not go out. There are many water inlet products and stiffeners on the valve cover. On the road, the role of watercourse and support, the caliber has single, double, multi-lobed, flanged and threaded connections.

working principle

The bottom valve is composed of valve body, valve disc, valve cover, bushing, sealing ring and other parts. Water from the water source enters the valve body from the valve cover. Under the pressure of the fluid, the valve disc opens the water. The pressure quickly closes the valve flap, and the liquid will not be poured back to the water source, which plays a role in unblocking pumping, saving water energy, and not damaging the pump.
