Product Name: Check Valve Assembly, 15 GPM, 60k (Part No. 301002-5)

Description:
This component is a complete, pre-assembled check valve unit specifically designed for 60,000 PSI (approximately 4,137 bar), 15 GPM waterjet intensifier pumps. The "301002-5" variant is manufactured for specialized, larger EF (Extreme Flow) intensifier configurations, distinguishing it from standard 60k units . As a complete assembly, it is ready for immediate drop-in installation, integrating both the inlet and outlet check valve functions into a single serviceable unit .

The check valve assembly is critical for converting the low-pressure water supply into a high-intensity cutting jet. It controls the one-way flow of water into and out of the high-pressure cylinder, ensuring that water is drawn in during the intake stroke and forced out to the cutting head during the compression stroke without dangerous backflow .

Applications:

• Serves as the primary flow control manifold at the high-pressure end of 60k, 15 GPM waterjet intensifiers.

• Specifically designed for H2O Jet's larger EF (Extreme Flow) intensifier systems .

• Houses the inlet (low-pressure) and outlet (discharge) check valves within the intensifier end cap .

Features:

• EF Series Specificity: Engineered for larger, high-flow intensifier systems (Extreme Flow) .

• Drop-in Ready: Supplied as a complete assembly, eliminating the need for individual component stacking during installation .

• Integrated Components: Contains the essential outlet body, poppet, spring, and inlet housing, simplifying replacement .

• Diagnostic Indicators: A temperature at the outlet fitting exceeding 49°C (120°F) indicates excessive back-flow through the outlet check valve .

Maintenance:

The need for check valve service is indicated by specific performance issues. If the hydraulic piston slams to the end of its travel, it indicates excessive back-flow through the inlet check valve. Repetitive spiking of the high-pressure water pressure indicates that one or both valves may be leaking excessively .

• Inspection: When servicing, inspect the Poppet Seat for damage or cracking. The seat is not symmetrical; the rounded side must face the Check Valve Body .

• Service Life: KMT recommends servicing check valves every 1,500 hours on a preventive schedule. The seat, spring, and poppet valve should be replaced as a set; if one component fails, replace all of them to ensure proper sealing .

• Torque Specifications: When reinstalling the Outlet Body into the Check Valve Body, torque the connection to 30 to 50 ft-lbs (41-67 Nm) .

• Safety Protocol: Severe injury can result if the machine is not properly locked out. Ensure the main electrical disconnect is in the OFF position, bleed down all high-pressure lines, and follow lockout/tagout procedures before service .
