Note: PN64 is the maximum allowable working pressure at ambient temperature. As temperature increases, pressure must be derated per ASME B16.34. PTFE packing has a maximum service temperature of approx. 200°C; graphite packing is required for higher temperatures.

Needle regulating / shut-off valve

End Connection

Twin ferrule – suitable for stainless steel or copper tubing

  1. الميزات الرئيسية
  • Needle stem tip – Provides precise flow regulation for very low flow rates
  • Twin ferrule connection – No welding required; reliable leak-tight seal; easy disassembly and maintenance
  • Stainless steel body – Excellent corrosion resistance
  • Blow-out proof stem – Ensures safety under high pressure
  • Replaceable packing – Easy online adjustment or replacement
  • Multiple stem tip options – Soft seat (PTFE/PEEK) or metal hard seat (sharp edge / blunt)
  • Bi-directional sealing – Can withstand pressure from both directions (arrow indicates recommended flow direction)
  1. Installation & Operation Instructions
  1. Ferrule installation – Insert tube fully into the ferrule socket. Hand-tighten the nut, then tighten with a wrench 1 – 1.25 turns from finger-tight (follow manufacturer’s instructions).
  2. Flow direction – An arrow on the body indicates recommended flow direction. The valve can be used bidirectionally, but pressure drop may differ slightly.
  3. عملية – Turn the handle clockwise to close, counterclockwise to open. Needle valves are designed for flow regulation; avoid long-term operation in fully closed or barely open positions.
  4. Maintenance – If external leakage occurs, carefully tighten the packing nut after depressurizing. If leakage persists, replace the packing.
