Double-door Bottom Valve Energy-saving Valve

It restricts the return of the liquid in the pump pipe to the water source, and has the function of only entering and exiting. There are many water inlets and reinforcements on the valve cover. Ribs, which are not easy to block, are mainly used in pumping pipelines. The role of water channels and supports. The caliber has single, double, and multi-flap types. There are flange connections and threaded connections. The bottom valve is estimated by the valve, the valve disc, The valve cover, bushing, sealing ring and other parts are composed of the valve cover. The liquid enters the valve body from the valve cover. Under the pressure of the fluid, the valve disc opens. It plays the role of smooth flow and energy saving.

Working Features:

◈In order to prevent the reverse flow of the medium, check valves should be installed on the equipment, devices and pipelines;
◈Check valves are generally suitable for clean media, and should not be used for media containing solid particles and high viscosity;
◈Generally, vertical lift check valves should be selected on horizontal pipelines with a nominal diameter of 50mm.
◈Used for water, gasoline, kerosene, diesel oil, etc.
