4 Things You Need To Know Before Selecting The Right Needle Valve

The importance of Needle valves in regulating the flow, pressure, and direction of fluid can’t be underscored. These Valves Have a point at the end of the valve stem. They have the ability to shut off the flow entirely.



They have been particularly designed to control the flow of liquid or gas so that it can be controlled gradually and could be eventually closed. These valves can control the flow of liquid in delicate gauges.Here are the following points you need to understand before making the right choice.

Pressure rating

The seat of the needle valve is designed to fit the needle exactly.It also provides a seal that operates at high pressure. The reason why a Needle Valve can withstand so much pressure is because of their size and shape. These valves work well when the precise flow of gas or fluid is needed. Different types of needle valves are designed for different pressure ratings. You should select the needle valve that can withstand high pressure.

Valve Size

It’s important to consider the valve size and end connection options. You can also achieve the above pressure rating with male and female connection ends. Choosing the right valve size will ensure a leak-free pipe system.

Operating Temperatures

Like any other component, Needle valve needs to operate efficient in a variety of functions. Choosing the right needle valve holds importance in the context that temperature can be extreme in certain industrial settings. It’s the packing in the needle valve that can determine the temperature it can withstand.

What makes Seal Excel’s needle valve a better choice

All needle valves are ISO 9001:2008, PED 97/23/EC and ATEX 94/9/EC certified and our in-house laboratory ensures that they are of high quality. They are suitable for application in a variety of industrial sectors such as oil, gas and petrochemical,sugar, textile and automobile. Our range of needle valves has been designed keeping durability and performance. These needle valves are available in a variety of sizes (1/4, ½, 1/8 inch).

Apart from that, they have low operating torque, forged body with straight and angled pattern. They come in the pressure rating of 5000-10000 psi which is quite good.


The efficiency of your pipe and tubing system depends a lot on needle valves. So, you can’t ignore its importance. Understanding these above points will certainly help in making the right choice.
