DIFFERENTIAL LOCK VALVE
The differential lock valve controls the supply of air to
the differential lock cylinder and to the control port of the
pilot valve. Depressing the pedal moves plunger (1)
and spool (2) down unseating valve (5) and allows air to
flow from supply port (6) out through delivery port (4) to
the locking piston and the pilot valve. Releasing the
pedal allows the valve to return, sealing supply port (6)
and allowing air to flow from the piston and pilot valve
out through exhaust port (3).
