Choosing Needles Valves for Your Applications? Consider This First

Similar to common industrial valves, needle valves are used to control flow. They have a construction as Needles Valvesgood as globe valves; however, needle valves are frequently utilized for accurate regulation of reduced flow rates. Most needles valves are small-sized to offer top-notch control of flow. They are extensively utilized for instrumentation control, shutting off the line, and regulating pressure for a broad range of applications.

Each and every needle valve must offer protected and leakage-free connections, but that’s just the starting.  Varying applications possess their own unique, individual needs.

When planning to buy needle valves, you need to pay heed to a few crucial factors. Stated below are some of the most vital aspects to consider before taking a final decision:

Pressure Ratings

The workable pressures offered by various kinds of needle valves vary based on the range of applications. Top performing needle valves usually bear pressures of about 5000 and 6000 psi at 100°F temperature. In scenarios where high levels of pressure are required, needle valves that can withstand about 10,000 psi at 100°F are easily available.

Size of the Valve

Comprehensively designed needle valves are quite easily found in an array of varying sizes and end-connection selections.  The pressure ratings stated above can be attained via male/female ends and in usual or metric dimensions.  Needle valves are frequently available in sizes from a range of 2 to 11 mm and average sizes of 1/8” to 1”.  When you pick an appropriate size, you will be assured of seamless and effective operations with lesser wear & tear and leakages.

Operating Temperatures

Just like common industrial components, needle valves are supposed to operate in a range of surroundings for effective functioning.  Temperature and a host of other things in industrial surroundings can be severe.  The packing utilized for needle valves usually aid in identifying endurable temperature ranges.

Here are the two most commonly utilized materials for increasing the temperature range of valves:

PTFE

Polytetrafluoroethylene is one of the finest known foundations of Teflon. When it is utilized for packing needle valves, PTFE offers added fortitude and opposition to soaring temperatures.  Average PTFE packing caters to temperatures ranging from -65°F to 450°F.

PEEKPEEK

Polyether ether ketone is a colorless natural thermoplastic polymer that is frequently utilized for engineering applications. It preserves chemical and motorized resistance traits to quite high temperatures.  When it comes to needle valves, PEEK can raise the temperature resistance up to 600°F when being utilized as extra packing.
