LESU Y-1512-A overflow valve protection oil circuit pressure adjustment control valve with mid-position return oil

Specification

Brand: LESU

Hydraulic control valve (with three -way function)

Note: The hydraulic oil circuit composed of an relief valve is added, which has the function of oil returns. No need to worry about the oil supply and installation when the cylinder rises to the top); adjustable oil pump pressure and higher playability.

The overflow valve is a hydraulic pressure control valve. In the hydraulic device, the pressure overflow, stabilization, system discharge and safety protection effects in hydraulic equipment. During the assembly or use, due to the damage of the O -shaped seal, the combined sealing ring, or the loosening of the screw and pipe joints, it may cause non -leakage.

Action of the relief valve:
Fixed pressure overflow: In the quantitative pump reunification adjustment system, the quantitative pump provides constant flow. When the pressure of the system increases, the traffic demand will be reduced. At this time, the overflow valve is turned on to make the excess flow overflow the fuel tank to ensure the import pressure of the overflow valve, that is, the pump outlet pressure is constant (the valve port is often turned on with pressure fluctuations).

Safety protection: When the system works normally, the valve is closed. Only when the load exceeds the specified limit (the system pressure exceeds the adjustment pressure), the overflow is turned on, and overload protection is performed, so that the pressure of the system will not increase (usually the adjustment pressure of the overflow valve is 10%to 20%higher than the system's highest working pressure higher than the system. .
