Product description

The BH-9631/OS is a specialized "Oversize" Short Feed Core Kit designed for Weaver and Rotary hydraulic valves that have undergone significant wear or specific legacy modifications. In some older lift systems, standard-sized cores may allow too much internal fluid bypass, resulting in poor lifting performance or creeping. This OS (Oversize) kit provides a tighter fit within the valve body, effectively sealing the hydraulic circuit and restoring original pressure levels. SVI International manufactures these cores to rigorous standards, ensuring they provide the precise flow control necessary for heavy-duty automotive lift operations. It is a critical component for specialized maintenance tasks where standard replacement parts no longer provide the required sealing tolerance.

Product highlights

• Enhanced Sealing: Oversize dimensions provide a superior fit for worn or high-tolerance valve bodies.
• Pressure Recovery: Helps restore full hydraulic pressure to the lift cylinders for heavy vehicle lifting.
• Specialized Application: Specifically tailored for M-1830OSC and related "OS" style valve assemblies.
• American Made: Precision engineered in the USA to ensure the highest level of metallurgical quality.
