Globe and needle valves are two of the most common industrial valves on the market today. Both are used in various industries, from manufacturing to oil and gas production. But how do you know which one is right for your specific application? In this blog post, we’ll look at the differences between globe and needle valves, so you can make an informed decision when choosing the right valve for your needs.
Globe Valve
Globe valves are named after their unique design, which features a circular body with a “globe” -a shaped disc that sits within it. This type of valve is used to control the flow of liquids or gases by opening or closing a passageway inside them. The globe-shaped disc can be opened gradually or completely closed off depending on what’s needed. Globe valves are typically used in applications requiring precise regulation, such as in chemical processing plants or power plants. They’re also good for controlling high-pressure flows because they can withstand higher pressures than other industrial valves.
Needle Valve
Needle valves are designed to provide accurate flow control through tiny passages, making them ideal for controlling low-flow rates and low-pressure applications. Unlike globe valves, which have a round disc that moves up and down to open or close a passage inside them, needle valves have a long stem with a needle tip at the end that can be adjusted to control the flow rate through small openings within them. Needle valves are commonly used in hydraulic systems where precise flow control is essential, such as in medical equipment or laboratory instruments. They’re also great for regulating gas pressure since they offer greater accuracy than other types of industrial valves.
Difference Between Globe Valve and Needle Valve
- Globe valves have a round body with a hole in the center that the stem passes through. The hole in the globe valve is usually much larger than the hole in the needle valve.
- Globe valves are designed to be used with fluids that are not very viscous, as the large hole in the center of the valve can cause turbulent flow.
- Needle valves have a long, thin stem with a small needle-like tip at the end. The small opening at the needle valve’s end allows for precise flow control.
- Needle valves are typically used with very viscous fluids, as the small opening at the end of the valve prevents turbulent flow.
- Globe valves are generally less expensive than needle valves, but needle valves offer greater control over the flow.
Conclusion:
When it comes to choosing between globe vs needle valves for your application, it all depends on what type of pressure and flow rate you need to regulate! Globe valves are better suited for high pressures and large flows, while needle valves work best for low and low flows. Understanding these differences is essential to make an informed decision when selecting the right valve for your needs! With this information from this blog post, you should now have all the knowledge necessary to choose between globe vs needle valve applications!
