Product Description
The HJ WATERJET HP Pneumatic Valve Stem, 60K (HJ-49865843) is a precision-machined internal component used within high-pressure pneumatic on/off valve assemblies in waterjet cutting systems.
This part functions as the valve needle (stem) that directly controls the opening and closing of the high-pressure water flow at the cutting head. It is a critical sealing and motion component, ensuring instantaneous response, tight shutoff, and consistent jet control.
The HJ-49865843 is specifically identified as the pneumatic valve stem within cutting head assemblies. It is a direct replacement for HJ-BV901184 (Discontinued).
Key Benefits
- Precision Flow Control – Ensures accurate jet start/stop
- Leak-Free Sealing – Tight interface with valve seat
- Fast Response Time – Immediate actuation during cutting cycles
- High Wear Resistance – Built for repeated high-cycle operation
- Improved Cut Quality – Eliminates dribble and delayed shutoff
Applications
- Abrasive waterjet cutting systems
- Water-only cutting heads
- Automotive manufacturing (precision trimming & cutting)
- Aerospace fabrication
- Industrial high-pressure cutting environments
