DBB multiple valve ball valve to replace the traditional line connection form of complex. Reduce leak in the system and achieve emissions fast, close the function. Double block double discharge ball valve utmost ground saves installation space.

To simplify the installation program. Reduce the pressure of pipe system. Convenient instrument clean and maintenance, reduce the cost. Products are widely used in electric power, petrochemical, metallurgy, Marine, oil, natural gas, coal gas, such as the pharmaceutical industry of hydraulic system in pipeline.

Flange double ball valve working principle:

In the pipes need to cut off, one only need to turn the sphere to cut pipe, another sphere only seating in the sphere of component failure before action. Also can alternate action of two spheres to make this product service life is longer, the pipeline used to double insurance, double cut off. Two high pressure ball valve a integrated, don't need to install temporary debug two ball valve flow centerline, also reduced the two high pressure ball valve series directly a connection point and a leak point in the installation, safe and reliable.
