The Advantages of Ultra High Pressure Shut-off Valves

What is a high-pressure shut-off valve?

The high-pressure shut-off valve is mainly used in industries that have high requirements for pressure. The conventional connection method is welding and threading. The high-pressure shut-off valve is mainly used in the chemical and pharmaceutical fields. Since it’s welded, it’s not convenient for replacement. It’s mainly suitable for occasions where the repair is not very frequent and the wear ratio is relatively low.

Sanitary shut-off valve is a kind of valve whose closing member (valve flap) moves along the centerline of the valve seat. According to this type of movement of the valve flap, the change in the opening of the valve seat is proportional to the stroke of the valve flap. Because the opening and closing stroke of the valve stem of this type of valve is relatively short and the shut-off function is very reliable, and because the change in the opening of the valve seat is proportional to the stroke of valve flap, which is very suitable for the regulation of the flow, this type of valve is very suitable for shut-off, regulation, and throttling.

The most prominent advantages of shut-off valve are:

1. During the process of opening and closing, as the friction between the valve flap and the sealing surface of the valve body is smaller than that of the gate valve, it’s very wearable.

2. The opening height is usually only one-fourth of the diameter of the valve seat passage, which is much smaller than that of the gate valve.

3. Usually there’s only one sealing surface on the valve body and valve flap, so the manufacturing technique is good and it’s easy to repair.

Meanwhile, the disadvantages of shut-off valves can’t be ignored. Its main disadvantage is the big flow resistance coefficient, which causes pressure loss. And in hydraulic devices, this kind of pressure loss is particularly obvious.
