NF Series Integral Forged Needle Valve, featuring minimal leakage points and suitability for harsh conditions including high temperature, high pressure, and high erosion.

1. Integral body structure;

2. Dual stem design: upper stem with threaded hardening, lower stem with smooth surface hardening;

3. Upper stem thread lubrication isolates system medium.

4. Non-rotating lower stem: linear operation (instead of helical) prevents damage to valve seat/valve tip and reduces packing-lower stem friction.

5. Optional panel mounting;

6. Dual high-lock bolts ensure durable, stable handle connection;

7. Handles available in multiple colors;
