Product Description
The HJ WATERJET On/Off Valve Maintenance Kit, 60K (HJ-001959-1 or HJ-302001-1) is a precision-engineered On/Off Valve Maintenance Kit for high-pressure on/off valve assemblies used in waterjet cutting systems operating up to 60,000 PSI (4,100 bar).
The HJ-001959-1 or HJ-302001-1 On/Off Valve Maintenance Kit is designed to restore the internal sealing system and actuation performance of the on/off valve—the component responsible for controlling the start and stop of the cutting stream at the cutting head.
Over time, internal valve components experience wear due to extreme pressure cycling, water erosion, and contamination, leading to issues such as leakage, slow response, or incomplete shutoff. The HJ-001959-1 or HJ-302001-1 On/Off Valve Maintenance Kit replaces those critical wear elements, restoring the valve to optimal performance and reliability.
The HJ-001959-1 or HJ-302001-1 include the following parts:
HJ-001328-1 or HJ-100061-1 On/Off Valve Poppet Seal
HJ-001337-1 or HJ-100062-1 On/Off Valve Backup Ring, Seal
HJ-A-0275-014 or HJ-400043-014 On/Off Valve O-Ring
HJ-A-0275-006 or HJ-400043-006 On/Off Valve O-Ring
HJ-006933-1 or HJ-100059-1 On/Off Valve Seat Poppet, SST
HJ-006934-1 or HJ-100060-1 On/Off Valve Poppet, SST
