🔧 K5V160DTP1F9R‑9Y04‑HV – Hydraulic Pump Regulator / Hydraulic Axial Piston Pump Control Component

K5V160DTP1F9R‑9Y04‑HV is a hydraulic axial piston pump assembly model commonly used as the main hydraulic pump in medium‑to‑large excavators and other heavy machinery. The “REGULATOR” part of the name typically refers to the internal pressure/flow regulating mechanism built into this pump assembly, which controls output flow and pressure within the hydraulic system.

⚙️ What It Is

• Part of the K5V160DTP series hydraulic pump family — specifically model K5V160DTP1F9R‑9Y04‑HV.
• Often supplied as the main hydraulic pump with integrated regulator for construction machinery.
• Found on excavator models (in some cases marketed under Kawasaki, Sumitomo, or aftermarket brands).

Note: “Regulator” in this context doesn’t refer to a standalone electrical or voltage regulator — it refers to the hydraulic pressure/flow regulating part built into the pump system that keeps pressure and flow at the correct level for safe, efficient operation. (Hydraulic regulators control fluid pressure/flow.)

⚙️ Function (What It Does)

Inside the hydraulic pump assembly:

• Regulates hydraulic pressure and flow rate delivered to the machine’s hydraulic circuits.
• Ensures the correct pressure is maintained for smooth and controlled operation of functions (e.g., boom, arm, swing, travel).
• Helps protect the hydraulic system from excessive pressure that could damage hoses, valves, or actuators.

The integrated regulator is essential for stable hydraulic performance under varying loads and speeds.

🏗️ Common Applications

This pump model (with regulator) is typically used as the main hydraulic pump in large excavators and similar heavy equipment, for example:

• Case / CNH machines such as CX350B, CX360B, CX370B (various excavator models).
• Similar axial piston pumps are also found on Sumitomo models like SH350‑5 (in aftermarket listings).
