Pneumatic Valve Repair Kit, NC, HP, 60K | HJ-05116025
The HJ WATERJET Pneumatic Valve Repair Kit, HP, Normally Closed, 60K (HJ-05116025) is a precision-engineered rebuild kit for high-pressure waterjet pneumatic valves, designed to restore performance in 60,000 PSI normally closed (NC) valve systems.
The HJ-05116025 Pneumatic Valve Repair Kit is engineered and built to include all critical wear components required to rebuild and restore valve sealing, response time, and reliability in demanding industrial environments.
Over time, valve internals wear due to extreme pressure, friction, and cycling, leading to leaks, slow response, or inconsistent cutting. This repair kit provides a cost-effective solution to bring the valve back to like-new performance.
Key Benefits
- Complete Valve Rebuild Solution – Restores full performance without replacing the entire valve
- Corrosion Resistance – Stainless steel components ideal for washdown and harsh environments
- Extended Valve Life – Reduces wear and increases durability under high-pressure operation
- Improved Sealing Performance – Prevents leaks and maintains consistent pressure
- Reduced Downtime – Fast, efficient rebuild minimizes production interruptions
Applications
The HJ-05116025 Pneumatic Valve Repair Kit is widely used across multiple industries, including:
- Waterjet cutting systems (metal, plastic, and composites)
- Food processing waterjet food cutting systems (hygienic and washdown environments)
- Automotive manufacturing (precision robotic cutting and trimming)
- Aerospace fabrication (high-accuracy materials processing)
- General industrial cutting operations
Frequently Asked Questions
- What is HJ Waterjet part number HJ-05116025?
HJ Waterjet HJ-05116025 is a High-Pressure (HP), Normally Closed (N/C) Pneumatic Valve Repair Kit for 60,000 PSI / 4,100 bar waterjet systems. It is a direct replacement for KMT 05116025.
- What does the HJ-05116025 repair kit include?
The kit contains the major wear components needed to rebuild the pneumatic valve, including the valve stem, valve seat, seal assembly, brass backup ring, stainless-steel backup ring, and O-ring.
- What pressure rating is HJ-05116025 designed for?
It is designed for 60,000 PSI (4,100 bar) high-pressure applications.
- Is HJ-05116025 normally open or normally closed?
It is a Normally Closed (N/C) pneumatic valve repair kit.
- What KMT equipment is compatible with HJ-05116025?
The kit is used with KMT-style 60K pneumatic valve systems. One documented compatibility list includes SL-IV, SL-IV Plus, SL-V, SL-VI, NeoLine, and TriLine systems.
- Is HJ-05116025 a complete valve or a repair kit?
It is a repair/rebuild kit, not the complete pneumatic valve assembly. It allows worn internal valve components to be replaced without replacing the entire valve.
- Does the kit include the stainless-steel backup ring?
Yes. The HJ-05116025 kit includes the components required to service the valve, and detailed parts listings identify both brass and stainless-steel backup rings.
- What tool is recommended for installation?
A seal installation tool kit, HJ-20470475, is recommended for installation.
- How do I know when HJ-05116025 needs to be replaced?
Common indications include leaking, poor valve shutoff, inconsistent valve operation, failure to hold pressure, or increased water leakage around the valve. Replacing the wear components can restore valve sealing and operation.
- Can I replace individual components instead of the entire HJ-05116025 kit?
Yes, individual components such as the valve stem, seat, backup rings, seal assembly, and O-ring are available separately in some parts catalogs. However, when several components are worn, replacing the complete repair kit is generally more practical.
- What is the difference between HJ-05116025 and HJ-05116017?
Both are associated with 60K pneumatic on/off valve repair kits, but HJ-05116025 is the Normally Closed (N/C) version, while HJ-05116017 as the Normally Open (N/O) version.
- What should I verify before ordering HJ-05116025?
Verify the part number (05116025), valve configuration (N/C), pressure rating (60K/4,100 bar), and your waterjet model/valve configuration. This helps prevent ordering the N/O version or a repair kit for a different pressure class.
