Therefore, H type or Y type slide valve reversing valve is often used. 24V solenoid valve reversing valve returns to neutral position, the steering motor will float, and then the foot brake to a smooth stop steering. Quality solenoid valve shows loader boom type hydraulic cylinder. Four-way directional valve in H position can translate the material or smooth the site, four-way bucket with the ground height rise that translation; In addition, when the system suddenly stops, the circuit can still shift the bucket smoothly. The reversing valve of the walking motor of crawler excavator adopts the reversing valve with the function of y-type slide valve, so that the walking motor can float in the process of digging without being subjected to the braking load. The choice of the middle position function of the rectifier slide valve has an important effect on the rectifier speed and vibration performance of the rectifier open vibration hydraulic system. When the slide valve is in the middle position, the four oil ports P, T, A and B are connected by H type three-position four-way directional valve to form A connected channel. The vibration wheel produces post-vibration due to its rotational inertia, which makes the compacted road surface under pressure. When the vibratory roller presses the subgrade, it has little influence on the compaction effect of the base, and also reduces the hydraulic impact force of the system.
