The function of hydraulic valve in four-column hydraulic press
The hydraulic valve is used to control the flow direction of the oil in the hydraulic system or adjust its pressure and flow, so it can be divided into three categories: directional valve, pressure valve and flow valve. A valve with the same shape can have different functions due to different mechanisms of action.
The pressure valve and the flow valve use the throttling effect of the flow section to control the pressure and flow of the system, while the directional valve uses the replacement of the flow channel to control the flow direction of the oil. That said, despite the variety of different types of hydraulic valves, they maintain some basic commonalities.
