Bleed-Down Valve Repair Kit | HJ-004694-1
The HJ WATERJET Hydraulic Auto Bleed Down Repair Kit, 60K (HJ-004694-1 or HJ-302008-1) is a precision-engineered maintenance repair kit designed to restore the automatic pressure relief (bleed down) function in waterjet intensifier pumps operating up to 60,000 PSI (4,100 bar).
The auto bleed down system is a critical safety and pressure management feature that automatically relieves trapped high-pressure water when the pump stops or cycles down. This prevents pressure from remaining locked inside the system, protecting both equipment and operators.
Over time, internal components within the bleed down assembly wear due to constant exposure to high-pressure cycling, contamination, and mechanical stress. The HJ-004694-1 or HJ-302008-1 Hydraulic Auto Bleed Down Repair Kit provides all necessary components to rebuild the system and restore proper pressure release function.
Key Benefits
- Restores Safe Pressure Release – Critical for maintenance and operation
- Protects System Components – Prevents overpressure damage
- Improves Reliability – Ensures consistent bleed down function
- Extends Equipment Life – Reduces stress on seals and tubing
- Prevents Downtime – Eliminates pressure-related failures
Applications
- Industrial waterjet cutting systems
- Automotive manufacturing (robotic cutting and trimming)
- Aerospace fabrication
- Metal and composite cutting
- High-production waterjet facilities
Frequently Asked Questions | HJ-004694-1
- What is HJ Waterjet part number HJ-004694-1?
HJ-004694-1 is a direct replacement for FLOW 004694-1 Hydraulic Auto Bleed Down Repair Kit on a 60K waterjet intensifier pump. Its purpose is to restore the valves ability to relieve trapped high-pressure water when the pump shuts down or cycles.
- What pump is HJ-004694-1 compatible with?
It is primarily associated with FLOW 60K legacy/ESL intensifier pumps.
- What are the equivalent part numbers?
Common cross-references include:
- FLOW: 004694-1
- H2O Jet: 302008-1
- KMT: 20458824
- TL reference: TL-001009-1
- Is HJ-004694-1 a complete bleed-down valve assembly?
No. It is a repair kit. The complete 60K bleed-down valve assembly is a separate part.
- When should the kit be replaced?
Typical reasons include a bleed-down valve that does not properly relieve pressure, leakage, worn seals/seat, or degraded valve performance during pump shutdown. The individual seals and valve components are service items.
- Can I buy the individual components instead of the complete kit?
Yes. Components such as the high-pressure seal, stem, seat, bushing, O-rings, and backup ring are available separately.
- What is the difference between HJ-004694-1 and HJ-001822-1?
HJ-004694-1 is the repair kit, while HJ-001822-1 is the bleed-down valve body/assembly component. They are not interchangeable part numbers.
- Is this a safety-critical part?
Yes. The bleed-down system is responsible for relieving residual high-pressure water, so servicing should be performed according to the applicable FLOW pump service procedures and pressure-safety requirements.
