Pneumatic Valve, Cutting Head Assembly, IDE II, 60K | HJ-20455902
The HJ-20455902 Pneumatic Valve Cutting Head Assembly IDE II 60K is a complete abrasive waterjet cutting head assembly engineered for precision cutting applications operating at 60,000 PSI (4,100 bar). This HJ-20455902 Cutting Head Assembly combines a permanently aligned diamond orifice system with a high-performance focusing tube and pneumatic valve arrangement to deliver consistent jet stream accuracy, longer component life, and superior cutting performance across metal, stone, glass, composites, and advanced manufacturing materials.
This ready-to-install assembly includes the IDE II-style cutting head assembly with integrated diamond orifice, focusing tube, 0.75" x 5.75" nozzle tube, ¼ HP inlet adapter, short stop filter, and a normally closed (N/C) pneumatic valve. By integrating critical wear and flow-control components into a single assembly, the unit minimizes installation time, reduces maintenance requirements, and ensures optimal abrasive waterjet operation in demanding production environments.
The HJ Waterjet HJ-20455902 Cutting Head Assembly utilizes an embedded diamond orifice that eliminates common alignment issues associated with conventional ruby or sapphire systems. The precision-engineered design maintains accurate water stream alignment through the focusing tube, reducing premature wear, improving cut quality, and extending service intervals. The integrated short stop filter further protects the cutting head from contamination while helping maximize diamond orifice life and overall system reliability.
Ideal for fabrication shops, aerospace manufacturers, stone processors, metal service centers, and industrial waterjet cutting operations, the HJ-20455902 Cutting Head Assembly delivers dependable performance, increased uptime, and reduced operating costs while maintaining quality and compatibility with KMT waterjet systems.
