The difference between manual knife gate valve and American standard globe valve

For all kinds of valves, many people may not know what they are, but in fact, valves are often used in our lives or in production, but we usually don't pay attention to them or don't know them. Next, let everyone know the difference between the American standard globe valve and the manual knife gate valve.

    The functions of the American standard globe valve and the manual knife gate valve are very similar. Both are used to cut off the medium. The following is a specific introduction for everyone:

    1. In appearance, the American standard globe valve is very similar to the manual knife gate valve, both with two interfaces and a hand wheel similar to a steering wheel.

    2. The disc of the American standard globe valve is parallel to the fluid, while the disc of the manual knife gate valve is a gate and perpendicular to the direction of the fluid.

    3. Their working principles are also different. The American standard globe valve is a rising stem type, and the hand wheel rotates and rises together with the stem, while the manual knife gate valve rotates the hand wheel and the stem rises.

    4. The installation method is different. When the American standard globe valve is installed, the medium can enter from the bottom of the spool and from the top. The flow direction of the manual knife gate valve is the same from both sides.

    5. Their resistance to fluid is also different. The flow resistance of American standard globe valves to fluid is greater than that of manual knife gate valves.
