The double - ball valve is designed to replace the complex forms of multiple valves in the traditional pipeline. Reduce the leakage point in the system, quickly realize the discharge and close the function. The double blockage double saves the installation space, simplify the installer, reduce the pressure of the pipe system, reduce the cost in the maximum limit.
The double - ball valve has the advantages of simple structure, reliable sealing, sealing surface and spherical often in the closed state, the media can not easily be eroded, easy operation and maintenance, suitable for water, gas, oil, solvents, acids and natural gas general working media, but also applies to poor working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various heavy industries. The valve body can be integrated and can be combined.
