Double block double discharge ball valve working principle: double block double discharge ball valve is supported by two pieces of seat a floating ball & # 65377; Under the pressure of the medium, the ball itself will produce certain displacement, so that the pressure to the seat ring, sealing effect & # 65377;

floating ball Industrial Valves according to the structure can be divided into one-piece ball valve structure, and split type ball valve structure & # 65377;

double block double multiple valve discharge ball valve is 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 in the hydraulic system of pipeline
