DN15-PN64-Ferrule Needle Valve

DN15 – PN64 – Ferrule Needle Valve

Technical Data Sheet

1. General Information

2. Design & Manufacturing Standards

3. Main Materials (Typical)

4. Outline Dimensions & Weight (Typical values – may vary by manufacturer)

 Dimensions above are typical references. Final dimensions to be confirmed with manufacturer’s drawing.

5. Pressure-Temperature Rating (Stainless Steel 316 body)

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.

6. Performance Data

7. 主な特徴

• 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)

8. 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. 手術 – 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.

9. Ordering Information

4. Stem tip sealing type (metal needle tip / PTFE soft tip)
5. Packing material (PTFE / graphite)
6. Valve configuration (straight pattern / angle pattern)
7. Media name, temperature, and pressure
8. Additional accessories (panel mounting nut, dust cap, etc.)
