A7 Auto-Return Log Splitter Valve  

(We have other valves available - if the schematic looks different than your valve, message us and we can substitute it)

Valve Specs:

Single spool, Open center.

  • Max pressure rating: 3500psi.
  • Relief valve set at 3100psi but is adjustable.
  • Working ports ½”NPT.
  • In/Out ports ¾” NPT
  • Detent Pressure set at 700 psi but is adjustable.
  • Compatible with most splitters (SpeeCo, MTD, Brave, Swisher etc)
  • Threaded end cap for easy detent adjustment


Mounting bracket holes (4) are 5/16-18 thread pitch and are spaced 1" x 2-5/8" apart

This is the next generation in log splitter 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.


 Bolts, Lock Washers, Nuts

  • Kit comes with the necessary fasteners to bolt the mount and pump together.  You'll supply your own engine mounting bolts
