Description
Technical Overview & Product Details
Flow control valves play a decisive role in maintaining the efficiency and safety of marine propulsion and auxiliary systems. The 147643-39621 is constructed to operate reliably within the high-vibration and high-temperature environments of a marine diesel engine. By managing fluid flow rates with high accuracy, this valve prevents system overload, reduces component stress, and contributes to the overall stability of the engine’s fluid-dependent systems.
- Compatible Engine Type: Yanmar marine propulsion and auxiliary engine series.
- Part Number / Designation: 147643-39621.
- Component Type: Flow Control Valve Assembly.
- Material: Corrosion-resistant materials selected for durability in harsh marine environments.
- Application: Fluid volume/pressure regulation within engine hydraulic or lubrication circuits.
Key Features & Performance
- Precise Flow Regulation: Engineered to deliver exact fluid flow parameters, ensuring consistent operational pressure across the engine’s fluid circuits.
- High Durability: Constructed from materials resistant to fatigue and fluid-induced corrosion, maintaining long-term functional integrity.
- Stability Under Load: Built to withstand the cyclic pressures and thermal stressors of heavy-duty diesel operation without performance degradation.
- Precision Engineering: Manufactured to meet strict OEM specifications, guaranteeing seamless integration and reliable operation within the engine’s existing control architecture.

Technical Maintenance Note:
When installing the 147643-39621, it is essential to ensure that the surrounding fluid lines and mounting surfaces are perfectly clean and free of debris. Use an appropriate torque setting for all connections to prevent housing distortion or leakage, as specified in the Yanmar service manual. Inspect the valve’s seals and O-rings for any signs of hardening or damage during installation. We recommend performing a system pressure check immediately after installation to verify that the flow rates align with the manufacturer’s performance requirements and that there are no signs of external leaks under operating conditions.
