Globe Valves
Learn all about Globe Valves
Isolating, regulating or controlling the flow of various fluids that pass through pipes and hydraulic systems. These are common needs in the industrial environment. But did you know that using a globe valve performs these tasks very efficiently?
This type of valve is normally used in frequent opening and closing operations, as well as in flow control at any desired level, which is why it is widely necessary in various processes.
Due to their application in a wide variety of processes, it is worth knowing the operating pattern of globe valves, their general characteristics and main advantages.
What is a globe valve and what is it for?
As previously stated, the globe valve is a device widely used in industrial environments.
This equipment is responsible for providing watertightness and blocking safety in hydraulic systems responsible for transporting fluids (steam, gases or liquids in general).
With this sealing capacity, the globe valve is widely used in equipment where there is a need to perform frequent opening and closing operations, preventing or releasing the passage of fluid.
It is also responsible for controlling the flow rate in the graduation, and can work not only in the open or closed position, but also in any intermediate closing position.
This device allows for great smoothness when opening and closing the handle under any operating conditions, mainly due to its reinforced construction and use of highly resistant materials, as they are designed to withstand high pressures.
Therefore, the globe valve's function is to interrupt the flow and isolate certain points in the line, steam outlets and boiler drainage points.
Where are globe valves used?
The globe valve is used in processes that require frequent opening and closing operations (preventing or releasing the passage of fluid). It also has the function of controlling the flow at any desired level.
With these characteristics, it is applied where there is a need to control the flow passage, and can be used in the regulation service in water, oil, liquid lines in general, as well as for steam, air and gases.
Therefore, these are areas where a globe valve may be necessary:
Sugar and Alcohol Industry
Energy Industry
Mining Industry
Pulp and Paper Industry
Oil Industry
Steel Industry
Petrochemical Industry
How does a globe valve work?
As seen previously, every globe valve has the function of regulating the flow of systems in which there is a need for constant opening and closing of the system.
But do you know how it works? To explain, it’s worth using an everyday example: a home shower.
In the shower, when you open the tap, the water flow increases and, when you close it, the volume tends to decrease. This is exactly how a globe valve works.
In this valve, the larger the opening, the greater the flow. On the other hand, the less the disc is raised, the smaller the amount of fluid that will pass, until the moment comes when the flow stops completely.
Given this characteristic, it is easy to see that the globe valve works with a linear movement, specifically designed to start, stop and regulate flow. In other words, the globe valve has the ability to allow gradual opening and closing. This reduces the throttling or opening speed, which minimizes the effects of water hammer.
MBX Globe Valve and its main advantages
Now that you know the characteristics and functions of the globe valve, it is time to understand its benefits. To introduce them, we will talk about the best valves on the market: the MBX Globe Valves.
One of their most significant benefits is that they allow efficient fluid regulation, with minimal wear due to erosion, both on the seat and the plug.
They feature different materials that make up the body, the castle and the internal components, allowing them to be used in corrosive or non-corrosive applications.
The MBX Globe Valve offers important advantages:
Cleaning the filter element becomes much faster and more efficient;
High efficiency in blocking residues, preventing them from spreading through the network, valve seats and water supply pumps, as well as many other equipment;
Allows the fluid to be blocked for possible maintenance within the hydraulic system;
It allows for a very significant economic gain within the installation, mainly by dispensing with accessories and connections for the installation of more equipment;
Protects valves and accessories installed after the shut-off valve, extending their useful life and eliminating damage caused by metal fragments and other particles that may be present in the pipes;
It can be applied over a wide range of pressure and temperature, working with the same efficiency;
Maintenance processes are facilitated by easy access to internal components, without the need to remove the valve from the line.
Types of globe valves
There are several models and features of globe valves on the specialized market. Therefore, see three types manufactured with the MBX quality standard.
MBX Straight Through Shut-Off Steam Globe Valve
The MBX Straight Port Shutoff Steam Globe Valve is offered in two models:
Model MBX Flange VGF-50 150/300 lb
Model MBX Weld VGS-50 300 lb
These MBX Globe Valves are used to interrupt flow, isolate certain points in the line, steam outlets and boiler drainage points.
They also allow for the filtration of waste. Furthermore, they can be applied to steam, water and other liquids compatible with their construction method.
Due to their construction characteristics, they are highly recommended for installations before boiler sludge discharge valves. It is worth remembering that these are the points that suffer most from the deposit of metal fragments and other types of unwanted particles that may be present in the pipes.
In addition to filtering waste, this globe valve will have the dual function of blocking before discharges for possible maintenance, also acting to prevent boiler drainage.

Straight-through steam shut-off globe valve with combined filter
Offered in the model MBX VGFFC-50 , the straight-through steam shut-off globe valve with combined filter is used to interrupt flow, isolate certain points in the line, steam outlets and boiler drain points. It also filters residues.
It is also recommended for installations before boiler sludge discharge valves, which are the points that suffer most from the deposit of metal fragments and other types of unwanted particles that are present in the pipes.
Because it has a combined filter, the straight-through steam blocking globe valve has the ability to assist in cleaning the filter element, offering greater efficiency and speed.
