MINIATURE NEEDLE VALVE

MINIATURE NEEDLE VALVE

A miniature needle valve is a compact flow control device designed for precise regulation of flow in small-diameter pipelines or confined spaces, commonly used in instrumentation, medical, laboratory, and pneumatic applications. These valves are characterized by their fine-threaded stem and narrow seat, which allow for accurate control of flow rate. Typically, miniature needle valves come in sizes ranging from 1/8 inch to 1/4 inch NPT (National Pipe Thread), though other thread standards such as BSP or compression fittings are also available depending on the application.

  • Compact design: Ideal for limited-space applications where full-size valves would not fit.
  • Precision flow control: Allows fine adjustments of fluid or gas flow using a tapered needle design.
  • Variety of connections: Available in NPT, BSP, and compression types for easy integration into various systems.
  • Durable construction: Often made from stainless steel, brass, or plastic to suit different operating environments.
  • Low leakage: Engineered for tight shut-off, minimizing leakage in sensitive systems.
  • Enhanced accuracy in flow regulation improves system efficiency and safety.
  • Space-saving design enables installation in compact setups without sacrificing performance.
  • Material versatility ensures compatibility with a range of fluids and gases, including corrosive media.
  • Ease of maintenance due to simple design and fewer moving parts.
  • Cost-effective solution for applications requiring precise flow management at a smaller scale.
