Engineered and Built for Reliable Operation in Extreme Pressure Conditions
Product Description
The HJ Waterjet Actuator Assembly, UHP, Normally Closed, 90K PSI (HJ-20474154)
is a precision-engineered KMT-style pneumatic actuator assembly used in ultra-high-pressure waterjet cutting systems. Designed to deliver fast, consistent actuation of the cutting head valve, this component ensures accurate control of water flow under extreme operating conditions.
Built for 90,000 PSI (6,200 bar) ultra-high-pressure systems, the actuator uses pneumatic force to rapidly open and close the valve, enabling instant response, improved cutting precision, and safe system operation. The normally closed configuration ensures the valve remains securely shut when not actuated, providing fail-safe performance and enhanced pressure control.
Compatible with KMT-style PRO I, PRO II, and PRO III cutting heads, the HJ-20474154 UHP Actuator Assembly plays a critical role in maintaining cut quality, operational efficiency, and reduced downtime in demanding industrial environments.
Manufactured to strict tolerances, it offers a durable, high-performance, and cost-effective actuator assembly, without compromising reliability
Key Benefits
- Ultra-High-Pressure Performance – Designed for 90K PSI systems
- Reliable Actuation – Ensures consistent valve response and cutting accuracy
- Enhanced Safety – Normally closed design prevents unintended flow
- Durable Construction – Built for high-cycle industrial environments
- Reduced Downtime – Reliable operation minimizes maintenance interruptions
Applications
The HJ-20474154 Actuator Assembly,UHP, N/C, 90K PSI is widely used in:
- Metal cutting (steel, titanium, aluminum)
- Aerospace manufacturing
- Food-grade waterjet processing
- Automotive fabrication
- Stone, glass, and composite cutting
- High-precision industrial machining
Why UHP Actuators Matter
Ultra-high-pressure actuator assemblies are critical because they:
- Control extreme-pressure water flow with precision
- Enable clean, accurate cuts without heat distortion
- Maintain system safety under extreme conditions
- Support high-speed automated production
Waterjet systems operating at 90K PSI require components like the HJ-20474154 to maintain performance and reliability under extreme stress.
