Relief valve (threaded connection)
1. product overview constant pressure overflow function: in the quantitative pump throttling system, the quantitative pump provides a constant flow. As the system pressure increases, the flow demand decreases. At this time, the overflow valve is opened to overflow the excess flow back to the tank to ensure the inlet pressure of the overflow valve, that is, the pump outlet pressure is constant (the valve port is often opened with pressure fluctuation). Stabilizing effect: the overflow valve is connected in series on the oil return road, the overflow valve generates back pressure, and the stability of the moving parts increases. Safety protection: when the system is working normally, the valve is closed. Only when the load exceeds the specified limit (the system pressure exceeds the set pressure), the overflow is opened for overload protection,

Relief valve (threaded connection)
1. Product Overview
Constant pressure overflow effect: in the quantitative pump throttling system, the quantitative pump provides a constant flow. As the system pressure increases, the flow demand decreases. At this time, the overflow valve is opened to overflow the excess flow back to the tank to ensure the inlet pressure of the overflow valve, that is, the pump outlet pressure is constant (the valve port is often opened with pressure fluctuation).
Stabilizing effect: the overflow valve is connected in series on the oil return road, the overflow valve generates back pressure, and the stability of the moving parts increases.
Safety protection: when the system is working normally, the valve is closed. Only when the load exceeds the specified limit (the system pressure exceeds the set pressure), the overflow is opened to carry out overload protection so that the system pressure will no longer increase (usually the set pressure of the overflow valve is 10% ~ 20% higher than the maximum working pressure of the system)
