GLOBE VALVES VS BUTTERFLY VALVES
GLOBE VALVE: A Globe valve is a valve regulates flow in a pipeline, it starts, control and regulates the flow of liquid or gas. Globe valves are spherical body in shape with movable disc and unmovable ring seat, these two halves are separated by an internal baffle, it has an opening that is stewed to shut the valve. Globe valves are used where the pressure drop through the valve is uncontrollable because they exhibit high-pressure drops when compared to other valves. The working principle of the globe valve is, when the handle wheel is rotated in a clockwise direction, the steam and valve plug will move downwards and the plug will be located between the two valve seats, therefore there will not be leakage of fluid when the valve is closed. On the other side, when the handle wheel is rotated in the anti-clockwise direction, steam and valve plug will move upwards, the valve will be opened and it allows the flow of liquid in the globe valve. Globe valves are highly useful in m...
