The CAT 5W-9408 is a Caterpillar one-way valve ball (spherical check valve ball), which is compatible with hydraulic/fuel system one-way valve assemblies. It uses a spherical seal to achieve one-way fluid flow and prevent backflow, ensuring stable system pressure and component safety. It is commonly used in engine fuel systems, hydraulic circuit control units, etc. It has a simple structure and excellent sealing and wear resistance.

Compatible Models CAT 320D/330D excavators, 950G/966G loaders, 3406E/C13 Engine check valves, used in fuel injection systems, hydraulic pump outlet check valves, and gearbox lubrication circuits, etc. Compatible valve seat model 5W-9409, matching spring model 5W-9410.
Performance Parameters: Working pressure 0-42MPa, working temperature -40℃ to 150℃, zero leakage sealing (pressure difference ≥0.1MPa), cycle life ≥100,000 cycles, suitable media viscosity 1-1000mm²/s.
Core Functions and Structural Features:
One-way fluid control: The spherical structure precisely fits the valve seat, allowing fluid to flow only in the forward direction. It automatically seals to block backflow in the reverse direction, preventing system pressure fluctuations and component damage, ensuring stable operation of the hydraulic/fuel circuit (Cat®…).
High-precision sealing: Made of 440C stainless steel, combining high hardness and wear resistance. The spherical surface is precisely ground, with strict control over roundness and surface roughness, suitable for long-term sealing under high-pressure conditions, reducing leakage risk and extending the life of the check valve assembly.
Suitable for various working conditions: Compatible with hydraulic systems, fuel systems, and other media environments in construction machinery, it can withstand high pressure, temperature fluctuations, and trace impurities in the medium, and is suitable for frequent start-stop and pressure change conditions.
Easy installation: Standard ball-shaped design, compatible with universal check valve assembly. Installation simply involves placing the valve seat and matching spring; no complex adjustments are required, improving assembly and maintenance efficiency.
