Technical Information

Frequently Asked Questions | HJ-1100020

1. What is HJ-1100020?
HJ-1100020 is a HJ Waterjet direct replacement part for BFT 1100020 Complete Suction Valve Assembly used on BFT high-pressure waterjet intensifier pumps. It controls water entering the intensifier and helps prevent reverse flow.

2. What are the alternate part numbers for HJ-1100020?
Common cross-references include:

• CP022109
• CP022109/844
• CP022844
  These references are associated with the same suction valve assembly.

3. What type of valve is HJ-1100020?
It is a suction-side check valve assembly, sometimes called a suction valve complete or inlet check valve assembly.

4. Where is HJ-1100020 used?
It is used in BFT high-pressure waterjet intensifier pump systems, including BFT pump families such as ECOTRON and SERVOTRON.

5. What does the suction valve do?
The valve regulates the inlet/suction flow of water into the intensifier and helps prevent backflow during the pump cycle. Proper operation is important for stable pump performance and pressure generation.

6. What components are included in the complete HJ-1100020 assembly?
The assembly incorporates components such as the suction-side body, valve seat, valve insert, lens, ball, and safety bolt.

7. What is the operating pressure rating?
Maximum allowable operating pressure of 400 MPa (4,000 bar), approximately 58,000 PSI.

8. What is the weight of HJ-1100020?
The complete assembly is approximately 388 grams.

9. Can I replace individual components instead of the complete valve?
Yes. Individual components associated with the suction assembly include the valve seat, lens, ball, valve insert, safety bolt, and union suction-side body. However, if several internal components are worn, replacing the complete assembly may be more efficient.

10. What are common symptoms of a worn suction valve?
Typical symptoms can include:

• Difficulty maintaining consistent pressure
• Pressure fluctuations
• Reduced pump performance
• Abnormal pump cycling
• Water leakage or backflow
• Increased wear of related valve components

11. Is HJ-1100020 the suction valve or pressure valve?
HJ-1100020 is the suction valve. The corresponding Pressure Valve Complete is HJ-1100039.

12. Should I replace the suction valve as part of pump maintenance?
It should be inspected during pump maintenance, particularly when pressure instability, leakage, or valve wear is observed.
