Two-way flow hard sealing rotary ball valve

1. Product Overview and Usage This is a patented product developed by Shanghai Mingjing Valve Co., Ltd. based on market demand based on years of experience in valve design, manufacturing, use and maintenance.
This valve can not only reliably cut off under forward pressure, but also reliably seal when reverse pressure or reverse pressure is much greater than forward pressure. The valve seal adopts the structure and principle of a hemispherical valve.
The shape adopts a butterfly structure, which has the characteristics of small size and light weight. It also has the properties of two-way hard seal, low sealing friction, durability, and light opening and closing. Therefore, , the cost performance
is much higher than that of the semi-ball valve. The successful development and application of this valve is a major technological innovation in the valve industry. Widely used in water pump outlets, pipe network systems, water recovery systems, high-level water tanks,
sewage systems that are prone to flooding, anti-backflow systems and other occasions that require two-way sealing. It can be used in metallurgy, mining, petrochemical, chemical, and electric power It is used for opening, closing and regulating pipelines in industries such as environmental protection and municipal administration.
In a two-way flow system, one of this valve is equivalent to two ordinary one-way sealing valves.
