Instrumentation Needle Valve

Introduction

The YNV01 Series Instrumentation Needle Valve from YDB Valve is designed for precise flow control in high-pressure and high-accuracy applications. With a finely threaded stem and robust stainless steel construction, it provides smooth, gradual regulation of flow, making it ideal for instrumentation panels, gas sampling systems, and chemical injection lines. The compact design and high-pressure capability ensure reliable operation even in demanding environments.

Engineered for versatility, the YNV01 offers various end connections, seat materials, and pressure ratings to suit a wide range of media and applications. Its leak-tight shut-off and corrosion-resistant body ensure long service life with minimal maintenance. Whether installed in laboratories, refineries, or industrial process lines, the YNV01 delivers reliable performance, safety, and precision control where it matters most.

Applications

Instrumentation Needle Valve is trusted across various industries for its precision, durability, and reliability. Explore its wide-ranging applications below:

    Testing

  • ✔Standard Test: Each valve is factory tested with nitrogen at 1000 psig (69 bar) for leakage at the seat and packing.
  • ✔Optional Hydrostatic test: This test is performed with de-ionised water at 1.5 time the working pressure.

    STEM TYPE

    YDB Needle Valves are available with choice of optional stem to provide greater flexibility.

  • ✔NON-ROTATING (NR) : It is Standard self centering non rotating stem tip typically used in high cycle application to extend the valve life.
  • ✔V-STEM (VS) : It is used for general purpose liquid and gases.
  • ✔SOFT SEAT (SS) : A soft seat stem requires a lower sealing torque, It is replaceable and suitable for temperature upto 120OC
  • ✔REGULATING STEM (RS) : It is used where some degree of flow control required.
