South American valve are leading Needle valve manufacturers in Brazil, Needle valves also known as plunger valves, are used for regulating flow and pressure with precision. They allow engineers to finely control water flow and pressure by moving a shaft that adjusts the position of a piston tube. This movement, facilitated by a gearbox, slides the piston tube to either open or close the valve, as needed by the control system.
Needle valves offer both manual and automatic operation. In manual mode, a handwheel adjusts the plunger's position relative to the valve seat. Turning the handwheel opens the valve by lifting the plunger, allowing fluid to flow.Conversely, turning the handwheel in the opposite direction moves the plunger closer to the seat, reducing flow or closing the valve. For automated operation, needle valves are connected to a hydraulic motor or air actuator. These components automatically open and close the valve, adjusting the plunger based on timers or external performance data obtained during machinery monitoring.
What is Needle valve used for?
In hydraulic systems, these valves play a vital role in controlling the flow of hydraulic fluid, ensuring the smooth and precise operation of machinery. Similarly, in pneumatic systems, needle valves regulate the flow of compressed air to achieve the desired pressure or speed of operation. Industries such as chemical processing and oil and gas also benefit from needle valves, using them to control the flow of corrosive or hazardous fluids safely and efficiently. Overall, needle valves are indispensable in systems where precise flow control is critical to ensuring the efficiency, safety, and reliability of operations.
Advantages:
The size of needle valves is smaller.
At low rates, the flow control is extremely accurate.
Accurate flow rate adjustments are possible.
They are capable of being throttled.
These valves are simple to shut off.
For the purpose of heating hot water, needle valves serve as bleed valves.
Needle valve manufacturers in Brazil. produces valves which are relatively simple in design, easy to install, and require minimal maintenance, making them a popular choice in many industries.
