Cast iron flap door - flap door

Cast iron flap doors are used for circular and square water outlets with unidirectional water flow. They have a tight structure, reliable operation, and do not require manual operation. The opening and closing force comes from the water source pressure. When the water pressure inside the cast iron flap door is greater than the external pressure, it opens; otherwise, it closes. The bolts or expansion wires of the cast iron door are made of stainless steel or carbon steel that has undergone anti-corrosion treatment, and the sealing components are made of rubber or rubber gaskets.
