Hydraulic Log Splitter Valve – 25 GPM, 3,500 PSI, Adjustable Detent, C5 Reverse Configuration

Single-Spool Open-Center Valve • Reverse Port Orientation • Adjustable Detent

The WSD31-286 C5 Hydraulic Log Splitter Valve is a heavy-duty replacement control valve designed for log splitters that use a reverse inlet, outlet, and work-port configuration. Rated for flow rates up to 25 GPM and operating pressures up to 3,500 PSI, this single-spool, open-center valve provides dependable hydraulic control for compatible splitter systems.

This valve is commonly used on certain Brave and Champion log splitters, although it may fit other brands and models with the same hydraulic layout. Its port orientation is reversed from the configuration commonly found on many SpeeCo, Husky, Oregon, Tractor Supply, and MTD log splitters.

The adjustable detent system allows the kick-out pressure to be fine-tuned for the application. As the detent balls and grooves wear over time, the threaded end cap allows further adjustment, helping extend the valve’s useful service life.

Important fitment notice: This is the less-common reverse port configuration. Carefully compare the inlet, outlet, A, and B port locations with your existing valve and the product photos before ordering.

C5 Reverse Configuration vs. Common A7 Configuration

The C5 valve uses the opposite port orientation from the configuration found on many common log splitter valves. Although the valves may look similar and share comparable pressure and flow ratings, they are not automatically interchangeable.

Before ordering, compare:

Inlet-port location
Outlet or tank-port location
A and B work-port locations
Handle orientation
Mounting-hole spacing
Hose routing

Important Installation Information

This valve is not universal. Verify that the port configuration, thread sizes, flow rating, pressure rating, mounting dimensions, and hydraulic circuit match your log splitter.

Hydraulic installation and pressure adjustments should be performed by someone familiar with hydraulic systems. Incorrect hose connections or excessive pressure settings may damage the pump, cylinder, hoses, valve, or other hydraulic components.
