  1. 2.  Auto-Return Adjustable Detent Log Splitter Valve


This valve is a 2-way operation Log Splitter valve

- Direction 1:  Actuate lever by hand, release it and it returns to neutral. 

- Direction 2:  Actuate lever by hand, release it and it stays in the actuated position (active) until the hydraulic cylinder bottoms out (or otherwise senses a spike in hydraulic pressure), at which time the detent will kick the lever back to the neutral position (inactive)

-  Single spool, Open center.

- Max pressure rating: 4000 psi.

- Relief valve set at 3100psi but is adjustable between 1000 psi and 4000 psi

- Working ports ½”NPT.

- In/Out ports ¾” NPT

- Detent Pressure set at 700 psi but is adjustable. (Detent accessed by removing end cap)

- Compatible with most log splitters (SpeeCo, MTD, Brave, Swisher etc) but can be used for any DIY hydraulics project

This is the next generation in 2 way hydraulic detent valves. The detent is usually what wears out and causes valves to fail. This valve allows user to adjust the kick out pressure to what they need and as detent balls and grooves wear.
