Product Description
The HJ WATERJET HP Check Valve Repair Kit (HJ-010642-1 or HJ-302003-1) is a comprehensive rebuild solution designed for inlet and outlet check valve assemblies used in waterjet intensifier pumps operating at 40,000 PSI, 60,000 PSI, and 94,000 PSI (87K nominal systems).
The HJ-010642-1 or HJ-302003-1 HP Check Valve Repair Kit restores the one-way flow control system that is critical to maintaining pressure, efficiency, and cutting performance. Check valves cycle continuously during operation, making them one of the highest-wear components in any intensifier system.
Over time, poppets, seats, springs, and seals degrade—leading to pressure loss, backflow, and inconsistent cutting performance. The HJ-010642-1 or HJ-302003-1 HP Check Valve Repair Kit replaces all critical wear components, restoring the valve to like-new operating condition.
The HJ-010642-1 or HJ-302003-1 HP Check Valve Repair Kit include the following parts:
HJ-A-0275-125 or HJ- 400043-125 Check Valve O-Ring (2)
HJ-004382-1 or HJ-100034-1 Check Valve - Poppet Seat
