A 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.
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.
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.
Sealexcel undertakes the manufacture of a large variety of high-quality SS 316 Needle Valves. The Stainless Steel 316 Needle Valves are specifically designed for positive leak shut-off as well as for the regulation of fluids in instrumentation, process and power applications. A wide range of port styles and sizes, temperature capabilities and pressures enables Sealexcel to provide the customers with SS 316 Needle Valves having the highest levels of flexibility during the design of miniaturized piping or tubing systems. Further, hydrostatic testing of the compact design and rugged construction is done for SS 316 Needle Valve to show endurance under 1.5 times the rated pressure and with nitrogen at 1000 PSI.
Every product manufactured by Sealexcel, including our SS 316 Needle Valves, is compatible with PED 97/23/EC, ISO 9001:2008, and ATEX 94/9/EC. Additionally, the In-House testing facilities at our company ensure and verify the high quality of manufactured products that are made available to every customer at a highly competitive price and in an extremely punctual manner.
The range of SS 316 Needle Valves manufactured by Sealexcel has been efficiently designed with the focus on durability and performance. The SS 316 needle valves are available in a range of sizes such as 0.25, 0.5 and 0.125 inches. Some examples are the INV01 series, BS01 series, BS03 series, BS05 series, BS99 series etc.
