Product Description
Product Overview
A globe valve, also known as a stop valve, is a type of sealing valve. When closed, pressure must be applied to the valve disc to ensure the sealing surface does not leak. When the medium enters the valve from below the disc, the operating force required to overcome resistance includes the friction between the valve stem and packing, as well as the thrust generated by the medium's pressure. The force to close the valve is greater than the force to open it, which is why the valve stem diameter needs to be larger, otherwise, the valve stem could bend. Globe valves are categorized by connection types: flange connection, threaded connection, and welded connection.
Since the development of self-sealing valves, the flow direction in globe valves has been modified so that the medium enters the valve chamber from above the disc. In this case, under the pressure of the medium, the force required to close the valve is smaller, while the force to open it is larger, allowing for a smaller valve stem diameter. Additionally, this configuration results in tighter sealing under the pressure of the medium. In China, valve standards specify that the flow direction for globe valves should be top-down. When a globe valve is opened, the disc reaches its fully open position once it has lifted 25% to 30% of the nominal diameter, at which point maximum flow is achieved. Therefore, the fully open position of the valve is determined by the stroke of the valve disc.
The opening and closing element of a globe valve (stop valve) is a plug-shaped disc with a flat or conical sealing surface. The disc moves linearly along the valve seat's centerline. The valve stem movement type (commonly referred to as "non-rising stem") may also include a rising and rotating stem. Globe valves can control the flow of air, water, steam, various corrosive media, slurries, oils, liquid metals, and radioactive media. As a result, these stop globe valves are well-suited for shutoff, regulation, and throttling purposes. Due to the relatively short stroke required to open or close the valve and its reliable shutoff capability, and because the change in valve seat opening is proportional to the stroke of the disc, globe valves are particularly suitable for flow regulation.
