Are You Using The Right Needle Valves?

Are You Using The Right Needle Valves?

Needle valves are ideal for accurate flow control, usually in high-temperature applications.

Needle valves are ideal for accurate flow control, usually in high-temperature applications. They also have shut-off capability.  To control or shut off the flow of fluid, the device lowers its stem inside the seat. Industrial processes where sudden fluid surges are common use needle valves widely. Without the best needle valve, repair, and replacement of delicate flow gauges would be frequent.

As you install or replace instrumentation valves, remember that enjoying the services of these gadgets depends on your selection. No single valve is one-size-fits-all- there are countless areas of application.

Industries for Needle Valves

Needle valves are common in oil & gas, refineries, chemical plants, power plants, and automotive among other industries. Often, they are used for controlling flow rates before fluids pass through delicate measuring instruments. Most applications need a constant flow rate that must sustain for some time. Some industrial pumps are controlled by governors and are prone to surge-induced damage. To protect the governors, these pumps will often feature a needle valve.

 

Different Materials Available

You may not err when selecting from a list containing bellows valves, ball valves, safety valves, and gate valves, but you may still pick the wrong construction material for your needle valve. Every valve comes with standard material, but there are options. The needle valve catalog contains pressure and temperature ranges, which can be helpful in selection. The material usually refers to the device housing, which can be carbon steel, stainless steel, brass, or exotic material such as Hastelloy, Inconel, and Monel, etc.


Temperature Range

Needle valves can work in both low pressure and high-temperature situations. You need to have the temperature range right to select the best needle valve. The best products have enhanced performance for higher temperature ranges. This calls for tough materials such as Polyether ether ketone (PEEK) and Polytetrafluoroethylene (PTFE).

Orifice/Port Size

Do you need a female or male connection? This is an important question, but it comes alongside consideration for the size of the device. With the correct parameters, chances of leakage or wear are minimal. Common port sizes are 1/8”- 1”, but this could vary according to the manufacturer.

Pressure Range

Choosing the pressure range is easier if you are sure about the plunger valve application. Most needle valves will have a range of up to 6000 PSI. To cater to extreme pressures, you can find needle valves with a capability of 10,000PSI. Note that temperature may affect working pressure inversely.
