DN15-PN40-NPT c/w Nipples SS Needle Valve

Stainless Steel Needle Valve – Technical Data Sheet

Size: DN15 | Pressure: PN40 | Connection: NPT with Nipples

1. Main Parts & Materials (All Stainless Steel)

2. Dimensions & Weight (Reference – Valve Body Only, without Nipples)

Note: Nipple length is typically 50 mm (2″) each unless specified otherwise.

3. Design Features

1. Non‑rotating Stem – Prevents galling and extends seat/packing life; stem moves axially without rotation.
2. Metal‑to‑Metal Seating (Standard) – Sharp needle tip provides fine flow control and positive shut‑off (bubble‑tight).
3. PTFE Packing – Low friction, good chemical resistance, suitable up to 200°C. Graphite packing available for high temperature.
4. Integral Bonnet Construction – Reduces potential leak paths; robust for high‑pressure applications.
5. Included Nipples – Valve is supplied with two stainless steel male NPT nipples for easy connection to piping or tubing.
6. Fine Flow Regulation – Needle profile allows precise, repeatable flow adjustment from fully closed to fully open.

4. Performance Characteristics

5. Aplikasi
