Principle of direction control travel valve:

Taking the slide valve type as an example, the relative movement of the valve core in the valve body changes the connection state of the oil port, realizes the switching of the hydraulic oil flow direction, thereby controlling the forward, reverse and stop of the travel motor, and achieving the purpose of controlling the travel direction of the equipment.

Principle of pressure control travel valve: Taking the Rexroth BVD balancing valve as an example, it belongs to the pilot hydraulic control valve. When the hydraulic system pressure oil enters the pilot control oil circuit, the valve core is pushed to overcome the spring preload force to move, open the main oil circuit, and allow the pressure oil to enter the main oil circuit to drive the actuator; when the pressure decreases, the spring resets the valve core to close the main oil circuit, and can also automatically adjust the pilot control oil circuit pressure to compensate for the pressure fluctuation of the main oil circuit to ensure stable movement of the load.
