Product Performance & Introduction
Restore Hydraulic Efficiency and Prevent Costly Pump Failure
Introducing our premium replacement Valve Plate, engineered specifically for the KOBELCO SK200-8 excavator’s main hydraulic pump, model K3V112DTP. This critical component is master-crafted to restore your pump’s original performance, eliminate inefficiencies, and protect your investment from further damage. If you’re experiencing hydraulic power loss or unusual pump noise, this valve plate is often the core solution.
Product Performance & Introduction
The Valve Plate is the heart of the axial piston pump’s pressure control system. In the K3V112DTP pump, it precisely directs the flow of hydraulic fluid, facilitating the smooth transition of pistons through intake and discharge cycles. After prolonged operation, the original valve plate develops wear, grooves, and scoring, leading to internal leakage (volumetric efficiency loss), pressure drops, and increased heat generation.
Our replacement Valve Plate is a direct-fit solution that reinstates the precise tolerances and smooth surface finish required for optimal pump operation. By replacing a worn valve plate, you directly address the root cause of many hydraulic performance issues, ensuring stable pressure, efficient operation, and extended pump life.

Frequently Asked Questions (FAQ)
Q1: What is the valve plate, and what does it do in the K3V112DTP pump?
A: The Valve Plate is a critical stationary part inside the K3V112DTP axial piston pump. It acts as a precision porting guide, controlling the intake of hydraulic fluid and the discharge of high-pressure fluid as the piston cylinder block rotates against it.
Q2: What are the symptoms of a worn valve plate in my SK200-8?
A: Key symptoms include:
-
A significant loss of hydraulic power and digging force.
-
Slow operation of all hydraulic functions.
-
A loud, knocking or whining noise from the hydraulic pump.
-
The hydraulic system overheating frequently.
-
Increased fuel consumption as the engine works harder to compensate for pump inefficiency.
Q3: Is this valve plate compatible with my KOBELCO SK200-8?
A: Yes, this Valve Plate is specifically designed for the K3V112DTP model hydraulic pump used in the KOBELCO SK200-8 excavator. It is crucial to confirm your pump model number before purchase.
Q4: Should I replace any other parts when I replace the valve plate?
A: Yes, it is highly recommended. During a pump overhaul, it is standard practice to also replace the piston/cylinder assembly (rotating group) and the thrust plate. These components wear in tandem. Replacing them as a set (often available in a kit) ensures a balanced repair and prevents premature failure of the new Valve Plate.
Q5: Is professional installation required?
A: Absolutely. Replacing the Valve Plate requires complete disassembly of the K3V112DTP hydraulic pump. This is a complex job that demands a clean environment, specialized tools, and expert knowledge. Incorrect installation can lead to immediate and catastrophic pump failure.
