Hydraulic cartridge valve RDHA-LWN direct action relief valve

The hydraulic balance valve is used to control the flow direction of the oil in the hydraulic system or to adjust its pressure and flow, which can be divided into three categories: direction balance valve, pressure balance valve and flow balance valve. The working principle is the anti-regulation in the valve body, when the pressure at the entrance increases, the diameter is automatically reduced to reduce the change of flow rate, and vice versa. If the reverse connection, this adjustment system will not work, because the regulating role is the valve disc, it has a directional, reverse pressure will reduce or even close the flow. Therefore, in use, to avoid the balance valve backloading human error
Balancing valve function:
Load holding: The balance valve prevents unwanted downward movement of the hydraulic cylinder, and the balance valve allows the operator to lift the weight at a certain speed and keep it in a certain position.
Load control: The balance valve can prevent the energy of the load of the actuator from triggering the action generated before the action of the hydraulic pump, thus eliminating the cavitation phenomenon of the actuator and the load runaway phenomenon.
Safe load: When the pipeline in the hydraulic oil circuit bursts or leaks seriously, the balancing valve installed on the actuator can prevent the uncontrolled occurrence of the moving load.
