Structure and Working Principle

The stainless steel needle valve is mainly composed of valve body, valve stem, valve core, valve seat, packing, and gland. The valve core is needle-shaped and cooperates with the valve seat to achieve precise sealing.

Principle: By rotating the valve stem, the valve core moves up and down, changing the gap between the core and seat. This allows for precise control or complete cut-off of the medium flow rate.

Key Performance Advantages

  • Excellent Sealing: Small contact area between core and seat ensures high sealing pressure even under extreme conditions.
  • Pressure Resistance: Stainless steel high-strength material withstands up to 70.0MPa.
  • Precise Control: Needle structure allows for micro-adjustment of flow rates.
  • Long Service Life: Superior corrosion and wear resistance ensures stability in harsh environments.
