Are globe valves suitable for intermittent use? Well, as a supplier of Globe Valve, I've got a fair bit of experience and knowledge to share on this topic.
First off, let's understand what intermittent use means in the context of valves. Intermittent use is when a valve isn't in constant operation. It's turned on and off at intervals, maybe for a short period each time, or it could be left open or closed for long stretches and then adjusted. This kind of usage is common in a lot of industrial and domestic settings. For example, in a water supply system for a small building, the valve that controls the water flow might only be opened when someone needs water and closed when they're done.
Now, let's dig into the features of globe valves that make them either a good or bad fit for intermittent use.
One of the key advantages of globe valves is their excellent throttling ability. Throttling is all about controlling the flow rate of a fluid. When you've got a process that needs precise control of how much fluid is flowing, like in a chemical mixing tank where you need to add a specific amount of a reagent at a time, a globe valve shines. In intermittent use scenarios, this throttling feature can be super handy. You can easily adjust the valve to get the right flow rate every time you open it.
The design of a globe valve also plays a big role. It has a disc that moves perpendicular to the seat, which gives it a tight shut - off. This is crucial for intermittent use because when the valve is closed, you don't want any leakage. Imagine a gas pipeline; if the valve doesn't close properly, it could lead to dangerous gas leaks. With a globe valve, you can be more confident that the flow will stop completely when it's shut.
However, there are also some downsides to using globe valves for intermittent use. One of the main issues is the wear and tear. Every time you open and close a globe valve, the disc rubs against the seat. Over time, this friction can cause the seat and the disc to wear out. If you're using the valve intermittently but with a high frequency of operation, this wear can happen relatively quickly. And once the seat or the disc is worn, the valve's performance can degrade, leading to issues like leakage or poor throttling.
Another thing to consider is the pressure drop. Globe valves generally have a higher pressure drop compared to some other types of valves, like Gate Valve. A pressure drop means that there's a loss of pressure as the fluid passes through the valve. In an intermittent use situation, this can be a problem, especially if your system is sensitive to pressure changes. For example, in a high - pressure hydraulic system, a significant pressure drop across the valve can affect the overall performance of the system.
Let's compare globe valves with Forged check Valve in the context of intermittent use. A forged check valve is mainly used to prevent backflow. It's a one - way valve that opens when the fluid is flowing in the right direction and closes automatically when there's a reverse flow. In some intermittent use cases, like in a pump discharge line where you want to prevent the backflow of fluid when the pump is stopped, a check valve might be more suitable. But if you need to control the flow rate as well as prevent backflow, a globe valve can be a better choice as it offers both functions.
So, are globe valves suitable for intermittent use? The answer isn't a simple yes or no. It depends on several factors. If you need precise flow control and a tight shut - off, and the frequency of operation isn't extremely high, then a globe valve can be a great option. But if you're worried about wear and tear, or if your system can't tolerate a high pressure drop, you might want to consider other valve types.
