Through the cooperation of the transition chamber, the buffer chamber, and the large-diameter valve body, the progressive flow diameter allows the valve inlet and outlet to gradually transition to the larger flow diameter inside the valve, avoiding flow interference caused by abrupt changes, reducing flow resistance, and the large-diameter design increases the channel diameter. The enlarged internal channel ensures that the fluid flows at a higher speed, further improving flow efficiency.
