Prevents damage to the hydraulic system caused by excessive pressure and plays the role of automatic pressure relief.
Two-way throttle valve:
Accurately control the flow rate of hydraulic oil, adjust the working speed of the bending machine, and ensure bending accuracy.

Working Principle
The working principle of the hydraulic valve group of the bending machine is based on the basic principle of the hydraulic system. The hydraulic pump supplies oil to the valve group through high-pressure oil. Various valves in the valve group (such as pressure control valve, flow control valve, reversing valve, etc.) adjust the flow and pressure of hydraulic oil according to system requirements and control the movement of actuators such as hydraulic cylinders and hydraulic motors.
Specifically, after the hydraulic oil is pumped to the valve group, it flows through each valve according to the control signal, adjusts the pressure, flow and direction, and drives the upper or lower die of the bending machine to move. The stability and accuracy of the hydraulic system are crucial to the processing quality and efficiency of the bending machine.
