Product ID: 10079580-4 – Dump Valve / Relief Valve Assembly

Description:
This component is a dump valve or relief valve assembly designed for waterjet cutting systems. It is a high-pressure control valve that rapidly diverts or releases pressurized water from the system to stop the cutting jet instantly. The “-4” suffix may indicate a specific version, port size, or pressure rating.

Applications:

• Used in waterjet cutting machines to stop the cutting jet rapidly during program pauses, tool changes, or emergency stops.

• Installed between the high-pressure pump or intensifier and the cutting head to provide on/off jet control.

• Suitable for both pure water and abrasive waterjet systems requiring fast, reliable pressure dump functionality.

Features:

• Constructed from high-strength, corrosion-resistant stainless steel or hardened alloy to withstand repeated pressure cycling.

• Designed for ultra-high pressure operation, typically rated at 60,000 psi (approximately 4,137 bar) or higher.

• Provides rapid actuation response, typically within milliseconds, for precise jet start/stop control.

• Includes precision-machined internal sealing surfaces and wear-resistant valve seats.

• May be pilot-operated or directly actuated depending on the specific system design.

• Engineered to vent high-pressure water safely to drain or tank when the valve opens.

Maintenance:

• Fully depressurize the waterjet system and disconnect power before servicing the dump valve assembly.

• Remove the valve from the system carefully, noting the orientation of inlet and outlet ports.

• Disassemble the valve according to the equipment service manual, taking care not to damage internal sealing surfaces.

• Inspect the valve seat and poppet or plunger for wear, erosion, cracking, or pitting caused by high-velocity water flow.

• Check all seals, O-rings, and backup rings for wear, extrusion, or chemical degradation.

• Replace any worn or damaged components with parts specifically designed for this valve assembly.

• Clean all metal components using a soft cloth and low-pressure water or compatible solvent; avoid abrasive tools.

• Inspect the valve body for cracks, corrosion, or thread damage.

• During reassembly, lubricate seals with manufacturer-recommended high-pressure grease.

• Tighten all threaded connections to the torque values specified in the service manual.

• After reinstallation, slowly pressurize the system and test the dump valve function repeatedly to ensure complete jet stop and no leakage.

• If the valve fails to close fully or leaks when closed, re-inspect the seat and seal condition.

• Replace the entire valve assembly if internal body damage or repeated seal failure occurs.
