Product overview
Forged steel globe valve is a valve whose closure (disc) moves along the center line of the seat. According to the movement of the disc, the change of the seat opening is proportional to the disc travel. Because the stem opening or closing stroke of this kind of valve is relatively short, and has a very reliable cut-off function, and because the change of the seat opening is proportional to the disc travel, it is very suitable for flow regulation. Therefore, this type of valve is very suitable for cutting or regulating and throttling.
The most obvious advantage is that in the process of opening and closing, the friction between the disc and the sealing surface of the valve body is smaller than that of the gate valve, so it is wearable. The opening height is generally only one fourth of the diameter of the seat passage, so it is much smaller than the gate valve. Usually there is only one sealing surface on the valve body and disc, so the manufacturing process is better and easy to maintain.

Product use
Forged steel globe valve is a commonly used cut-off valve, which is mainly used to connect or cut off the medium in the pipeline, generally not used to regulate the flow. Globe valves are suitable for a wide range of pressure and temperature. The valve is suitable for small diameter pipelines. The sealing surface is not easy to wear and scratch, and the sealing performance is good. When the valve is opened and closed, the disc travel is small, the opening and closing time is short, and the valve height is small.
