All about needle valves
March 20, 2020Needle valves manufacturers in India, needle valve manufacturer
June 9, 2021A needle valve has a small port and a needle-shaped plunger that is generally threaded. The needle valve 
permits precise regulation of the flow of fluids, even though it is usually capable of handling relatively lower rates of fluid flow.
Applications of Needle Valves
Although needle valves are mostly used in piping systems, they can also be utilized in vacuum systems. They are also used in cases where there is a need for precise control of the flow of gas at low pressure. This includes filling vacuum tubes, gas lasers and other such devices with gas.
Needle valves are generally utilised in flow-metering applications, particularly in cases where a low, constant and calibrated rate of flow is needed to be maintained for a period of time, e.g. idle fuel flow inside a carburettor. Small and simple needle valves generally find use as bleed valves in a number of water-heating applications.
What are Stainless Steel Needle Valves?
Stainless steel is a general term for a group of alloy steels that are resistant to corrosion and contains at least 10.5% chromium. Every form of stainless steel has a high degree of corrosion resistance. The resistance from attack is usually due to a chromium-rich oxide film that is formed on the surface of the steel. Even though the layer is extremely thin, this inert and invisible film is bound firmly to the metal and offers protection against an extensive variety of destructive media. The film self-repairs rapidly in the presence of oxygen. Needle valves made of stainless steel ensure that damage arising from abrasion due to fluid or even corrosion due to environmental factors is highly minimised.
