Introducing the Ball Check Valve: The ball check valve is widely used in sewage systems as a type of check valve. Its unique construction overcomes various issues caused by the difficulty of sealing sewage. The valve body is made of ductile iron and coated with epoxy resin through electrostatic spraying. The ball is primarily made of 304 stainless steel and is externally covered with EPDM rubber, effectively preventing seal failures due to rubber detachment. Due to its special structural principle, the ball can freely fall within the valve cavity, allowing for both horizontal and vertical installation. This design effectively prevents sealing problems caused by foreign objects getting stuck.
