  • Model GP-CBN is a HI/LO hydraulic gear pump with 12 different displacement combinations with maximum pressures of 900 psi for the low pressure pump and 3000 psi for the high pressure. The change from LO to HI pressure is automatic with the LO side pressure pre set from 400 psi to 900 psi.

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.

Pump to Mount Bolts, Lock Washers, Nuts

  • Includes the required bolts, nuts and lock washers required to mount the pump to the mount.  You'll supply your own engine mounting bolts.
