4. Working principle of cast iron globe valve.
When we control the steering wheel of the valve, the valve disc will be raised or lowered from the original position. Depending on the type of globe valve, the disc can be machined into many different shapes. By changing the shape of the disc, the flow rate when opening the valve changes significantly.
When the valve disc is in the sealing position, the septum between the two halves in the valve body is equivalent to the closed state of the valve. When operating the handwheel control, the steering wheel will act on the valve stem to lift the valve disc out of the baffle position, allowing the fluid to pass through the gap above the baffle equivalent to the fully open state of the valve.
