How does a needle valve work?

Needle valve design

Its function, like the great majority of valves, is to regulate the fluid that passes through a circuit safely and efficiently. The needle valve owes its name to its design, characterized by having a conical rod that acts as a plug over a hole with a diameter much smaller than the nominal diameter of the valve itself. .

How does a needle valve work?

Using the steering wheel you can control the distance between the plunger and the seat. Being of fine thread the movement is slow so that many turns are required to achieve a total opening. This gives the valve superior accuracy, stability and sealing. In addition, it gives it great wear resistance as it prevents vacuum aspiration at high differential pressures. These features make needle valves ideal for protecting delicate meters from possible damage caused by sudden changes in pressure. They are generally used for systems that work lighter and less viscous materials with low flow rates.

Needle valve uses

Inglés Needle valves are generally used in low pressure hydraulic systems, chemical processing and other gas and liquid services. These valves can also be applied to the high temperature and oxygen service depending on their materials. Needle valves are usually made of stainless steel, bronze, brass or metal alloys. It is important to choose a needle valve made with the material that best suits the service you need. This will help preserve the life of the valve and keep your systems running smoothly and safely.
