Product Description

Bottom Valve
   The bottom valve is also known as the check valve, is a low pressure plate valve, its role is to ensure that the liquid in the suction pipe one-way flow, so that the normal work of the pump when the pump intermittent stop working, so that the liquid can not return to the water box, ensure that the suction pipe is full of liquid, in order to facilitate the start of the pump.

   Foot Valve or Bottom Valve, is actually a check Valve, plays a role in preventing water flow back.

   Bottom valve according to the material can be divided into plastic bottom valve and metal bottom valve, can also be divided into ordinary bottom valve and backwash water bottom valve.

   The bottom valve is mainly used in water pumps and other mechanical equipment to deal with slurry. Usually, the bottom valve will be installed at the bottom of the underwater suction of the water pump to prevent slurry backflow.
