94K Universal On/Off Valve Body (HJ-014554-1) – HJ WATERJET Replacement Part for 87K/94K Systems
The 94K Universal On/Off Valve Body (Part # HJ-014554-1) is the stainless-steel housing designed for Flow-style universal on/off valve assemblies used in 87,000 PSI and 94,000 PSI waterjet cutting systems. As the primary structural component of the cutting heads high-pressure valve assembly, this precision-machined body maintains proper alignment of critical sealing components, ensuring reliable valve operation, rapid shutoff response, and long service life.
Engineered to withstand the extreme pressures generated in modern waterjet cutting applications, the valve body supports the seat, poppet, seal, and backup ring assembly while maintaining consistent water flow control during every cutting cycle. Replacing a worn, washed-out, or damaged valve body helps restore factory performance, reduce leakage, eliminate slow reseating, and improve overall cutting accuracy.
Key Features
OEM Flow Precision Manufacturing
Manufactured for direct replacement compatibility with universal 87K and 94K on/off valve systems. Precision tolerances ensure proper alignment and sealing performance.
High-Strength Stainless Steel Construction
Built from premium stainless steel to resist erosion, washout, corrosion, and fatigue caused by ultra-high-pressure waterjet operation.
Optimized for Extreme Pressure Applications
Designed specifically for Flow-style waterjet systems operating at pressures up to 94,000 PSI, maintaining structural integrity under demanding industrial cutting conditions.
Restores Cutting Head Performance
Replacing a damaged valve body restores proper seat-to-poppet alignment, improves sealing efficiency, and reduces nozzle weeping and inconsistent cutting performance.
Direct Fit Replacement
Compatible with Flow-style Universal On/Off Valve Assemblies used across numerous waterjet platforms and cutting head configurations.
Applications
The HJ-014554-1 Universal On/Off Valve Body is commonly used in:
- Flow 87K Waterjet Systems
- Flow 94K Waterjet Systems
- HyperJet Cutting Heads
- Universal On/Off Valve Assemblies
- Abrasive Waterjet Cutting Systems
- Industrial Metal Fabrication
- Aerospace Component Manufacturing
- Stone and Glass Processing
- Precision Waterjet Machining Operations
Compatible Components
For optimal performance, HJ waterjet recommends replacing associated wear components during valve body service, including:
- On/Off Valve Seat (HJ-014558-1)
- On/Off Valve Poppet (HJ-014557-1)
- On/Off Valve Seal (HJ-014556-1)
- Backup Ring (HJ-014555-1)
- Universal On/Off Valve Seal Repair Kit (HJ-014988-1)
Installing new sealing components together helps maximize valve life, improve reseat performance, and reduce the risk of leakage caused by mixing worn and new parts.

Why Replace a Worn On/Off Valve Body?
Over time, ultra-high-pressure water flow can erode sealing surfaces and internal passages, causing:
- Water leakage or weeping
- Delayed valve closure
- Reduced cutting consistency
- Premature seal wear
- Increased maintenance costs
- Lower cutting efficiency
Replacing the valve body before severe wear occurs helps maintain optimal waterjet performance, maximize consumable life, and reduce unplanned downtime.
