Valve for Steam Globes

How do steam globe valves work?

Typically,van cầu hơi nóng steam globe valves are used to control the flow of steam. Steam globe valves control fluid flow by opening, closing, and throttling. As well as controlling the flow of steam, these valves also regulate steam pressure. The steam globe valve is used in many different applications such as pharmaceuticals, food, and power plants. As these valves are used in applications such as sanitary (such as food and pharmaceuticals), they release steam into the product so that it can be cleaned up. The body of a steam globe valve is constructed from a strong metal material. As a result, the body is able to withstand extreme pressures and temperatures, including 700 degrees Celsius. Cast iron, ductile cast iron, stainless steel, and carbon steel are some of the materials used by manufacturers to make the body of steam globe valves. Manual or automatic steam globe valves are available. Valve operators operate manual steam globe valves using handwheels, while valve actuators operate automatic ones. Steam globe valve actuators include electric, pneumatic, and hydraulic components.

Valves for steam globes are composed of the following components 

Wheel of hand 

When the valve operator applies force, the steam globe valve opens, closes, or regulates fluid flow. A steam globe valve is controlled by a handwheel. An actuator controls fluid flow by opening, closing, or regulating valves automatically. 

Bodies of valves 

Steam globe valve components are housed in this component. The valve bodies of steam globe valves are designed using different types of metallic materials to enhance their strength against high temperatures, high pressures, and impact damage from falling objects. 


An integral part of a steam globe valve that protects the stem and stem sealing materials from damage. When fluid flow is opened, throttled, or closed, the bonnet contacts the stem threads to rotate the stem. A bolt, screw, weld, or union connection connects the bonnet to the body.


Discs are connected to handwheels and actuators by stems. Discs open, close, or regulate fluid flow based on torque transmitted from the handwheel to the stem. 

The disc 

This component is used to close, open or regulate the flow of fluid in a steam globe valve. Discs are connected to actuators and handwheels through stems in order to receive torque from them. 

The seat 

These valves are designed with two seats by steam globe valve manufacturers. It is the seats that are responsible for regulating or stopping the flow of fluid through steam globe valves. 


The packing covers the stem with sealing material. Fluid leakage via the stem is prevented by the packing used by manufacturers of steam globe valves. It is necessary to replace the packing material after a certain period of time.

An enclosure 

The cage surrounds the disc in a steam globe valve. In the steam globe valve, there is a cage. By moving the valve disc, more openings in the cage are exposed, increasing fluid flow. It is highly influenced by the arrangement of cage openings and the design of the cage that fluid flows. To ensure efficient sealing, the cage in a steam globe valve guides the valve disc into the seat.
