Working principle of ductile iron bar pressure reducing valve?
Compressed air with a pressure of P1 is input from the left end and throttled through valve 10, with the pressure dropping to P2 at the output. The magnitude of P2 can be adjusted by adjusting springs 2 and 3. Rotating knob 1 clockwise compresses springs 2 and 3 and diaphragm 5, causing valve core 8 to move down, increasing the opening of valve 10 and thus increasing P2. If knob 1 is rotated counterclockwise, the opening of valve 10 decreases, and P2 decreases accordingly.
