Question by: Hubert Y on Jan 27, 2026, 9:10 PM
Will this valve work alright on my log splitter?
Answer by: Customer Support on Jan 29, 2026, 12:02 PM
This valve is designed for metered flow, meaning the flow is directly proportional to the movement of the lever, which should work well for a log splitter application.
