    DVQ eccentric hemispherical valve with a hemispherical shape is an ideal design. When the valve is opened or closed, the eccentric action can be used to prevent the sealing surface from being directly connected to the spherical surface, which can effectively improve the service life of the valve, and effectively prevent the valve from opening under high temperature but cannot be closed or closed. But can't open the situation.

           This series of ball valves are divided into sensory seals and soft seals according to the sealing performance. This product is widely used in electric power, petroleum, chemical, paper, light defense, food, manufacturing, aerospace and other fields.
