A load-sensitive multi-way valve is a valve that feeds back the change signals of pressure, flow and power to the valve to realize the control function. It can automatically adjust the flow according to the load change to maintain the stability and efficiency of the system. The load-sensitive multi-way valve is usually equipped with a pressure sensor to monitor the hydraulic pressure changes in the system in real time.
