Introduction to Needle Valves
Needle valves are a type of valve used to regulate flow in a piping system. They are characterized by a long, tapered needle - like plunger that fits into a small orifice. This design allows for very precise control of fluid flow, making them ideal for applications where accurate flow regulation is crucial, such as in laboratory equipment, instrumentation, and high - pressure hydraulic systems. Needle valves can handle a wide range of fluids, including liquids and gases, and are available in various materials like brass, stainless steel, and carbon steel to suit different operating conditions.
