Overview:
1. When the valve is often closed for safety valve. When the valve pressure is less than a certain limit value, the valve does not overflow. When the valve before the pressure exceeds the limit value, valve immediately opened, the oil that flows back to the tank (or the low pressure loop), so it can prevent overloading of the hydraulic system and the safety to protect oil pump and hydraulic systems.
2, the overflow valve often open when the overflow valve. The valve with the throttle element and the load in parallel, with the amount of oil required for different oil, the valve overflow when small, so that the pressure in the hydraulic system to maintain constant.
