Lifting Bottom Valve DN65/DN80/DN100
Lifting bottom valve is an energy-saving valve, generally installed at the bottom end of underwater suction pipe of the water pump. It restricts the liquid returning to the water source. The valve cover has a plurality of water inlets and reinforcing ribs. It is not easy to block, mainly used in pumping pipelines.
The lifting bottom valve is composed of valve body, flap, cover, bushing and sealing ring. The water enters the valve body from the valve cover. The flap opens the water under the fluid pressure, and quickly closes by the outlet pipe pressure when the water is stopped. The liquid will not be returned to the water source, which makes pumping smoothly and saves water energy loss.
