When a hydraulic system of Hydraulic Elbow Machine has multiple hydraulic cylinders, it is necessary to connect a valve at the pump outlet to ensure that each hydraulic cylinder can be both normal and quiet when there is nothing wrong with it.

It is best to install an electromagnetic spill valve. This valve can control the pressure of your entire system. When the cylinder does not rise pressure above the nominal pressure, the pressure can be opened. Under the nominal pressure, the valve can close the hydraulic cylinder. It can be easily controlled by electronically controlled overflow.
