The advantages of copper ball valve and stainless steel ball valve: the fluid resistance is small, and the resistance coefficient is equal to that of the pipe section of the same length; the structure is simple, the volume is small, and the weight is light; it is tight and reliable. It has also been widely used in China; easy to operate, quick to open and close, only need to rotate 90° from fully open to fully closed, which is convenient for remote control; easy maintenance, simple ball valve structure, sealing rings are generally movable, and it is convenient to disassemble and replace ; When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium will not cause erosion of the valve sealing surface when the medium passes; it has a wide range of applications, from small to several millimeters, to several meters, from high Vacuum to high pressure can be applied.
How to use copper ball valve and stainless steel ball valve: make sure that the pipeline and valve have been flushed before operation; the operation of the valve drives the valve stem to complete rotation according to the input signal of the actuator: when the valve rotates 1/4 turn (900) in the forward direction, the valve Shut down. When the reverse rotation is 1/4 turn (900), the valve opens; when the direction indicator arrow of the actuator is parallel to the pipeline, the valve is open; when the indicator arrow is perpendicular to the pipeline, the valve is closed.
