WA350 WA420 Excavator Accessories Excavator solenoid valve 714-07-16730

◆ Safety locking solenoid valve: When the locking rod is put down, the safety locking solenoid valve is in the energized state, and the pilot oil circuit 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 is relieved by rotating the horse to the brake piston.

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

◆ Working device pressurization solenoid valve: It 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: When the forearm performs the recovery action, the forearm speed is accelerated.
