Product Description
The HJ WATERJET HP Check Valve Repair Kit (HJ-302003-2) is a complete rebuild solution designed for inlet and outlet check valve assemblies used in H20 Jet waterjet intensifier pumps operating at 40,000 PSI, 60,000 PSI, and 94,000 PSI (87K systems).
The HJ-302003-2 HP Check Valve Repair Kit version is an updated or alternate configuration of the standard check valve repair kit, engineered to deliver reliable sealing, improved wear resistance, and consistent flow control across multiple pressure platforms.
Check valves are among the most critical and highest-wear components in a waterjet system. The HJ-302003-2 HP Check Valve Repair Kit replaces all key wear elements to restore proper one-way flow, pressure retention, and system efficiency.
