Product Description

Overflow effect of constant pressure: the quantitative pump throttle system, the quantitative constant flow pump is provided. When the system pressure increases, the traffic demand will decrease. When the relief valve opens, the excess flow back to the tank overflow, ensure the relief valve inlet pressure, the pump outlet pressure constant (often with the pressure fluctuations valve port open).
Stabilizing function: relief valve in series in the oil return line, the pressure relief valve, the moving parts increases stationarity.
System unloading effect: an overflow valve small flow string in the remote opening of relief valve, when the electromagnet power, remote control opening of relief valve through the tank, when the hydraulic pump unloading. The relief valve as the unloading valve.
Safety protection: the system work properly, the valve closed. Only the load limit exceed (the system pressure exceeds the set pressure) on the overflow, overload protection, the system pressure does not increase (usually make the relief valve set pressure adjustment than the maximum working pressure system high *0% ~ *0%).
