Pneumatic Valve Repair Kit, HP, NO, 60K | HJ-05116017
The HJ WATERJET Pneumatic Valve Repair Kit, HP, Normally Open (NO), 60K PSI (HJ-05116017) is a precision-engineered rebuild kit for high-pressure waterjet dump valves, designed to restore performance in 60,000 PSI normally open pneumatic valve systems.
Designed specifically for normally open (NO) pneumatic valves the HJ-05116017 Pneumatic Valve Repair Kit includes all critical internal wear components required to rebuild the valve, restore sealing integrity, and ensure consistent high-pressure flow control in demanding industrial environments.
Over time, valve components wear due to extreme pressure, high cycle rates, and continuous operation, resulting in leaks, slow response, or inconsistent cutting.The HJ-05116017 Pneumatic Valve Repair Kit provides a cost-effective solution to return the valve to like-new operating condition.
Key Benefits
- Complete Valve Rebuild Solution – Restore performance without replacing the full valve
- Reliable Sealing Performance – Prevents leaks and pressure loss
- Extended Valve Life – Reduces wear and maintains efficiency
- Reduced Downtime – Quick rebuild minimizes production interruptions
- Cost-Effective Maintenance – Lower cost vs. full valve replacement
Applications
The HJ-05116017 Pneumatic Valve Repair Kit is widely used in:
- Waterjet cutting systems (metal, plastic, composites)
- Automotive manufacturing
- Aerospace fabrication
- Food processing waterjet systems
- General industrial cutting operations
Frequently Asked Questions | HJ-05116017
1. What is HJ Waterjet part number HJ-05116017?
HJ-05116017 is a direct replacement for KMT 05116017 Pneumatic Valve Repair Kit, HP, Normally Open (N/O), 60K. It is commonly used to rebuild the high-pressure pneumatic dump/on-off valve on KMT waterjet systems.
2. Is HJ-05116017 normally open or normally closed?
Normally open (N/O). This is an important distinction because HJ Waterjet also offers HJ-05116025, which is the corresponding 60K normally closed repair kit
3. What is the difference between HJ-05116017 and HJ-05116025?
HJ-05116017 = Normally Open (N/O)
HJ-05116025 = Normally Closed (N/C)
Both are HP 60K pneumatic valve repair kits, but they are intended for different valve configurations.
6. What KMT-style pumps use HJ-05116017?
The kit is associated with several KMT-style pump platforms, including NeoLine, SL-IV, SL-IV Plus, SL-V, SL-VI, and Tri-Line configurations.
HJ-05116017 is also listed with its NEO 30 and 50 HP 60K pumps and within certain SL-VI 60K pump configurations.
7. Is HJ-05116017 a complete dump valve?
No. It is a repair/rebuild kit, not the complete pneumatic valve assembly. HJ Waterjet lists the pneumatic valve body separately as HJ-10189181.
8. Is HJ-05116017 a dump valve repair kit?
Yes. HJ-05116017 is identified as the HP Pneumatic Valve, N/O, 60,000 PSI repair kit, and it is also specified as the Dump Valve Repair Kit.
9. What are the common symptoms of a worn HJ-05116017 valve?
Typical symptoms can include:
- Difficulty maintaining or releasing high pressure
- Water leakage around the pneumatic dump valve
- Valve failing to open or close correctly
- Pressure fluctuations
- Reduced cutting performance
- Increased machine downtime
A worn seat, stem, seal, backup ring, or O-ring can contribute to valve performance problems.
10. What tools are recommended for installing HJ-05116017?
A seal installation tool kit, HJ-20470475, is recommended by HJ Waterjet for installing the valve seals correctly.
11. Can I buy the components individually?
Yes. Components such as the valve seat, stem, seal assembly, backup rings, and O-rings are also available individually. However, HJ-05116017 packages the components needed for a complete pneumatic-valve rebuild, making the kit convenient for scheduled maintenance.
12. Is HJ-05116017 the same as a 90K pneumatic valve repair kit?
No. HJ-05116017 is for 60K / 4,100 bar systems. Different part numbers are used for its 90K / 6,200 bar pneumatic valves, including HJ-20477518 for normally open 90K systems
13. What should I verify before ordering HJ-05116017?
Confirm these four items:
- Part number: 05116017
- Valve type: Normally Open (N/O)
- Pressure: 60,000 PSI / 4,100 bar
- Application: KMT-style high-pressure pneumatic/dump valve
This is especially important because HJ-05116017 and HJ-05116025 look similar in application but have different N/O vs. N/C configurations.
