Parts of an SS Needle Valve

Do you know what are three primary variants of needle valves are?

There are three main variants for needle valves depending on the location of the needle.

• a straightforward screw-down valve (T-type needle valve)
• a more direct flow route is provided by an oblique needle valve (angle pattern),
• regulated exit flow that is perpendicular to the main flow.

Use of SS Needle Valve

• A needle valve is included into every analogue field equipment to regulate the flow of fluid.
• When the flow has to cease gradually, needle valves are useful.
• The needle valve can function as a throttle and on/off valve.
• When metering applications for steam, air, gas, oil, or water are necessary, this can be employed.
• When a very low flow rate is needed, a needle valve is useful for sampling sites in pipes.
• Gas bleeder lines can utilise this valve.
• In automated combustion control systems where precise flow management is necessary, needle valves are employed.
• To lessen the variability in the pump discharge, it is utilised with constant pressure pump governors.

SS pneumatic needle valves Advantages

• This valve makes it possible to control flow at extremely low rates with greater accuracy.
• The size of needle valves is smaller. Therefore, there won’t be a space problem when it’s installed.
• With this valve, throttling is feasible even with small fluid volumes.
• Flow rates may be accurately changed.
• It is simpler to use.

Disadvantages of Needle Control Valve

• The high fluid flow restriction causes a high pressure loss in the needle valve.
• They are only suitable for pipe systems with modest flow rates.
• If the fluid contains solid particles, the seat and needle may be harmed.
• Simply looking at the handle position cannot determine whether it is open or closed.
• These kinds of valves cannot be opened or closed immediately. Immediate actions may harm the need valve’s seat.

What is the advantage of precision needle valve?

The advantages of precision 1/2 inch stainless steel needle valve are:

• The precision needle valve helps with flow control at a very low rate and high accuracy.
• They are small in size, and thus the space can never be a constraint.
• With high precision needle valve, throttling is possible even with a less fluid volume.

How to choose the right needle valve?

Factors to keep in mind to choose the right needle control valve are:

• You should choose the valve with the correct pressure rating, something that the valve is capable of handling.
• Also, consider the size of the water flow control needle valve and the connection option.
• Selecting the right valve for the ideal temperature is crucial. For example, the high temperature needle valve will show good performance in various high temperature services.

Ss 304 needle valve vs ss316 needle valve

The difference between ss304 and ss316 needle valve lies in their chemical composition. The latter also has molybdenum in its composition. While the ss 304 needle valve is an affordable choice for moderate corrosive environments, the ss316 products offer higher resistance to corrosion and pitting due to chlorides.

Are pneumatic needle valves directional?

The pneumatic needle valves are bi-directional, which means they can control flow in both directions and not only one.

How does a ss needle valve control air flow?

The airflow can be controlled by the ss needle valve by tightening it. This reduces the airflow and backs it up inside the actuator, preventing it from generating further pressure due to high resistance. The mini needle valve can reverse the flow or maintain a constant flow inside the system.
