Loader excavator transmission solenoid valve 6008815

The role of excavator solenoid valve

Safety locking solenoid valve: When the locking rod is down, the safety locking solenoid valve is in the energized state, and the pilot oil line is connected after the solenoid valve is switched.

Rotary brake solenoid valve: The rotary solenoid valve is powered off when operating the rotating action, the valve core is not switched, and the pilot oil circuit releases the brake by rotating the horse to the brake piston.

Travel 1/2 speed solenoid valve: travel speed of 1 speed and 2 speed switch.

Working device pressurization solenoid valve: there is a working device pressurization, improve the digging strength.

P2 unloading proportional valve: control the opening state of P2 unloading spool, so that the hydraulic system does not participate in the work of the pressure oil back to the hydraulic tank, eliminate the residual pressure of each actuator.

Walking diameter proportional valve: in the compound action operation, maintain the walking straightness.

P1 unloading proportional valve: control the opening state of P1 unloading spool, so that the hydraulic system does not participate in the work of the pressure oil back to the hydraulic tank, eliminate the residual pressure of each actuator.

Forearm 2-speed reverse ratio valve: Increases the forearm speed when the forearm performs the recovery action.
