Pressure Valve Complete | HJ-1100039 | Complete Union Pressure Side
The HJ-1100039 Complete Union Pressure Side, also known as Pressure Valve Complete CP022047/844, is a critical high-pressure component used in BFT waterjet intensifier pumps. The HJ-1100039 complete pressure valve assembly regulates and maintains ultra-high-pressure water flow on the outlet side of the pump, ensuring consistent cutting performance, system efficiency, and operational reliability in demanding industrial waterjet applications.
Manufactured to withstand extreme operating pressures, the assembly integrates all essential wear and sealing components into a single ready-to-install unit. The HJ-1100039 complete assembly includes the pressure-side union, valve seats, lens, valve insert, ball, spring, and safety bolt, providing a comprehensive solution for maintenance, repair, and pump rebuild operations.
Designed for compatibility with BFT Ecotron, Servotron, Semperdur, and other BFT intensifier pump systems, the HJ-1100039 pressure valve assembly helps maintain optimal pressure control, minimizes downtime, and extends the service life of the waterjet pump. Regular replacement of worn pressure valve components is essential to prevent pressure fluctuations, reduced cutting accuracy, and premature wear on high-pressure pump systems.
Engineered for demanding industrial environments including metal fabrication, stone cutting, aerospace manufacturing, automotive production, and precision waterjet machining, the HJ-1100039 assembly delivers dependable performance under continuous high-pressure operation.

Frequently Asked Questions | HJ-1100039
What is Part Number HJ-1100039?
1) HJ-1100039 is HJ Waterjet direct replacement part for BFT 1100039 Complete Pressure Valve Assembly for BFT high-pressure waterjet intensifier pumps. Its older BFT reference is CP022047/844.
2) Is HJ-1100039 a Pressure Valve or Suction Valve?
Pressure valve. The corresponding complete suction valve is BFT 1100020.
3) Can I buy the individual components instead?
Yes. The valve seat and lens are wear parts, and the individual components are also listed separately by waterjet parts suppliers.
4) How do I know whether I need the complete HJ-1100039?
If multiple internal components are worn, damaged, or the valve assembly has been in service for an extended period, replacing the complete pressure valve assembly can reduce maintenance time and ensure the internal components are replaced together.
If only a specific wear component is damaged, the individual component may be replaceable.
5) What are common symptoms of a worn pressure valve?
Common symptoms can include:
- Unstable high pressure
- Pressure fluctuations
- Reduced cutting performance
- Water leakage
- Poor pump efficiency
- Increased wear on related valve components
These symptoms can have other causes, so the complete pump/valve system should be inspected before replacing parts.
6) How many HJ-1100039 valves are used in a BFT intensifier?
There are 2 pressure valves (HJ-1100039) per intensifier.
7) What BFT pumps use HJ-1100039?
The Ecotron and Servotron configurations. For example, BFT Ecotron 38 and Servotron replacement-parts listings identify HJ-1100039 as the Pressure Valve Complete.
8) Is HJ-1100039 interchangeable with HJ-1100020?
No. They are different assemblies:
- HJ-1100039 = Pressure Valve Complete
- HJ-1100020 = Suction Valve Complete
