Water Jet Pump Parts – 3‑Way 2‑Pressure Valve, 56 mm, Model No. 10153500-Waterjet-Pump-Parts-3-Way2-Pressure-Valve-56.919.3-1

Introduction, Application, Features, and Maintenance:

This component is a 3‑way, 2‑pressure valve designed for water jet cutting pump systems. It features three connection ports with a 56 mm interface and is configured to selectively direct high‑pressure flow between two different pressure circuits, enabling switching between operating pressures within the machine.

Application:
Used in the high‑pressure pump and distribution system of water jet cutting machines to switch between two pressure levels. Typical installations include selecting between cutting pressure and standby/bypass pressure, or directing flow to different cutting heads or circuits that operate at different pressures.

Features:

• Rated for extreme pressures common in water jet cutting, up to 6,000 bar (87,000 psi).

• 3‑way configuration with all ports at 56 mm interface size.

• Dual‑pressure capability allows switching between two preset pressure levels.

• Provides reliable flow path switching with minimal pressure drop.

• Manufactured from high‑strength, corrosion‑resistant material suitable for abrasive water jet media.

• Precision‑machined internal passages ensure smooth flow and minimise turbulence.

Maintenance:

• Regularly inspect the valve body, all three ports, and internal sealing surfaces for signs of erosion, cracking, or wear.

• Check for leakage at all connection points during machine operation.

• Operate the valve periodically to ensure smooth switching action and proper seating.

• Monitor pressure consistency; pressure fluctuations may indicate internal wear or seal failure.

• Replace immediately if any surface pitting, thread damage, internal leakage, or pressure loss is detected.

• Always use compatible seals and washers when reassembling.

• Follow specified torque values for all three connections.
