Vertical check valve (vertical installation type) is used to prevent reverse flow of pipeline medium. It automatically closes by the self weight of the valve disc or the reverse pressure of the medium, without the need for external drive. The valve body is often made of corrosion-resistant materials such as cast steel and stainless steel, and the internal structure is divided into two types: lifting type (vertical movement of valve disc) and rotary opening type (rotating opening and closing of valve disc). It has the characteristics of low flow resistance, high sealing, and high pressure resistance, and is widely used in water supply and drainage, petrochemical, and boiler systems to avoid equipment damage caused by medium backflow. It needs to be installed vertically to ensure functional effectiveness.
