The working principle of 10K Japanese standard flange ball valve is to rotate the valve core to make the valve smooth or close. Ball valve switches are lightweight, small in size, can be made into large diameters, reliable in sealing, simple in structure, easy to maintain, and the sealing surface and spherical surface are often in a closed state, which is not easily eroded by media. They are widely used in various industries. Two piece flange ball valves have their own unique advantages, such as frictionless switches, seals that are not easily worn, and small opening and closing torque, which can reduce the size of the actuator they are equipped with.
