Why Purchase On Off Globe Valve From BCST
On Off Globe Valve -FAQ
What is the difference between On-Off Globe Valve and the control valve?
When working with a fluid control system, you need a valve to ensure the system’s smooth working. You have the choose a valve according to your choice from dozens of valves available on the market. Each valve may be used for precise functions.
So many people feel it difficult to differentiate between the On-Off Globe Valve and the control valve. Both these valves serve different purposes. The usage of these valves depends upon how much control you need for your system. Control valves are more accurate, and on the other hand, On-Off Globe Valves are more all, or you can say nothing. So let’s test the distinction in detail:
As you can understand by the name, the control valve controls liquid flow in a system. You can maintain the variable flow at specific set points, including concentration flow rate, density, pressure, temperature density, and liquid levels. The control valve has a valve frame., actuator, positioner, trim elements, and frame assembly.
A control valve may contain actuators that can be hydraulic, pneumatic, or electrically powered. They manage how the valve opens and closes.
On-Off Globe Valve is not a very accurate instrument as a control valve. It ultimately allows the flow or completely shuts off flow. There are different styles of on-off valves. On-Off Globe Valve is one of them.
What are the blessings and downsides of On-Off Globe Valves?

What is the working principle of the on and off globe valve?
The working of the On-Off Globe Valve is to handle the flow of fluid or gases. When there is no pressure or when there is no air, then the valve gets on automatically. And there may be a rubber tube in the valve frame. And this rubber tube squeezes while you place the stress on the final the ON-OFF GLOBE VALVE ON –OFF GLOBE VALVE also opens when the force is applied. The piston in the rubber tube helps the fluid flow straightforwardly when the rubber tube is pulled. And when there is no pressure, it will return to its previous position.

What is the difference between On-Off Globe Valve and an off-gate valve?
The on-globe valve is different from the on-off gate valve in many ways; let’s see how these valves are different from each other in detail:
First of all, let’s test how they’re one of a kind in structure:
Structure:
The length of the on-off gate valve is shorter than the length of the On-Off Globe Valve. And its height is more than On-Off Globe Valve. When you install an on-off gate valve, you should pay attention to the size of the valve, and when you install On-Off Globe Valve, you should pay attention to the space where you are going to install the valve. The On-Off Globe Valve is tightly closed by the sealing according to the pressure so that you can get the effect of zero leakage. When the valve is opened and closed, the valve sealing and seat are interconnected; they get rubbed with each other. So it will be straightforward for the sealing surface to wear out. When the on-off gate valve is near to close, the pressure difference between pipelines is significant. Which makes the sealing surface wear more seriously?
What are the characteristics of On-Off Globe Valve?
On-Off Globe Valve is essential for many industries. The valve is also known as a cut-off valve. The valve’s stem is on the axial side as the valve is sealed. The clack of the valve applies pressure, making the sealing surface of the valve, which stops the material from leakage between the sealing surface.
The On-Off Globe Valve sealing pair has a flap sealing surface and seat, and the stem moves the valve flap and moves vertically in the middle of the valve seat. When the valve opens and closes, the opening height is not so considerable, so you can easily adjust the flow. And you can easily manufacture and maintain with the help of the On-Off Globe Valve, and the pressure range is also more than other valves that are commonly used.
As the on-off globe valve has on-off features, it closes the flow entirely, and then it remains tight in the direction of flow. So you can get incredible tightness and low flow resistance qualities when the valve is in open condition. They don’t open and close fully. And the opening height is not so significant. So you can quickly produce and maintain it. The sealing floor does not have any harsh impact, ultimately freed from put on. During the opening and closing of the On-Off Globe Valve, the valve disk and sealing surface don’t have any connection. Therefore, the sealing surface doesn’t have any harsh impact, remaining free of wear.
What are the requirements and specs of On-Off Globe Valve?
Standards and specifications:
Design | Conform to |
Manufacture | DIN3356,EN13789 |
Dimensions | EN1092-2, ANSI B16.5 |
Face to face dimensions | EN558-1,API 594,DIN 3356 |
Testing | EN12266-1API598 |
What is the assessment of the globe valve with different valves?
An On-Off Globe Valve uses a multi-turn motion type, and the stem moves the valve disk in a straight direction. On the other hand, an on-off Gate valve also moves straight, but it has a straight-through material movement. An on-off gate valve lowers the plug, which blocks the way of the flow and doesn’t need any medium to change them to change the way. When it opens completely, an on-off gate does not have a shallow head loss(L/D=῀8). They cannot organize and regulate flow because of an increase in head loss, and it will make the gate of the gate valve wear out. On the other hand, an On-Off Globe Valve will not wear for a more extended time.
Who is the producer of On-Off Globe Valve?
In China, BCST is the top On-Off Globe Valve manufacturing and supplier brand, which has gained world-class fame and popularity through the production of highly efficient On-Off Globe Valve. And now, it gained worldwide popularity. The company has been exporting On-Off Globe Valve to over 100 countries for the last 20 years. On-off- Globe valve is a tool utilized in tight final programs that might be operating for vapours, liquids, or gas. It contains a temperature extension and metal bellows seal. The design of this valve is according to the modular assembly principle, and it may contain a solenoid valve and limit switches. ON -OFF GLOBE VALVES are used to start the flow of material entirely, or they may also use them to stop the flow of material throughout the process. This kind of On-Off Globe Valves is suitable for industries handling liquids or gases.
How can you select the exceptional On-Off Globe Valve for your application?
On-Off Globe Valve can give you the perfect solution for your industry to adjust the flow, but you don’t show any interest in the quantity of pressure loss, i.e.:
- Cooling water applications
- Oil fuel applications
- Drains, boilers, and vent applications
- Drain and sprinkle applications etc.
On-Off Globe Valve selection:
- You should choose the design of your On-Off Globe Valveaccording to your system’s configuration needs.
- You should select the material which matches your system.
- The seal material of your On-Off Globe Valveshould be proper.
- You should select the suitable actuator for your On-Off Globe Valve, which will meet your system’s needs.
- The size of the On-Off Globe Valveshould follow your system needs.
How to calculate the amount of warmth loss in the On-Off Globe Valve?
Head loss is pressure loss, or you can say it is friction loss. This problem can be seen in the system when the medium changes the directions two times when it passes through the system. So, when you want to measure the heat loss, you should use the co coefficient L/D. This coefficient can be used for comparing On-Off Globe Valve to the section of the pipe. L is for length, and D is for diameter. An On-Off Globe Valve, which contains L/D=5, will create the same head loss as a pipe with the same L/D, which means all are equal.
For a typical On-Off Globe Valve, linear ones have L/D=῀340, and a common 90-diploma On-Off Globe Valve has an L/D=῀150.
You should also measure you’re On-Off Globe Valve’s VK and CVs.
You must be thinking about what is VK and CV.
What is a VK:
You must know that VK indicates liquid or gas flow passing through the On-Off Globe Valve and pressure drop.
What is a CV:
It is water’s flow rate in gallons per minute when the temperature of the water is 60 degrees F, and its pressure drop is one psi.
Final words:
On-off- Globe valve is a device used in tight closing applications that would be working for vapours, liquids, or gas. It contains a temperature extension and metal bellows seal. The design of this valve is according to the modular assembly principle, and it may include a solenoid valve and limit switches.
