    Points for attention

    Proportional valves adjust hydraulic or power parameters by electronic reference signals. The basic principle of proportional valve: the corresponding reference signal generates the corresponding electromagnet suction, and the electromagnet suction acts on the spool that is returned by the spring, driving the spool movement, so as to achieve the required hydraulic parameter adjustment. DLHZO type valve is a high performance servo proportional valve, direct acting, valve sleeve construction, with LVDT position sensor, according to the input electrical signal to provide direction control and flow control without pressure compensation, valve sleeve construction, direct acting, with position sensor,IS4401 standard,06 diameter and 10 diameter.

    Constant pressure overflow effect: In the quantitative pump throttling regulation system, the quantitative pump provides a constant flow rate. When the system pressure increases, the flow demand will decrease. At this time, the relief valve is opened, so that the excess flow flows back to the tank, to ensure that the relief valve inlet pressure, that is, the pump outlet pressure is constant (the valve port is often opened with pressure fluctuations). Safety protection: When the system is working normally, the valve is closed. Only when the load exceeds the specified limit (system pressure exceeds the set pressure), the overflow is turned on for overload protection, so that the system pressure is no longer increased (usually the set pressure of the relief valve is 10% to 20% higher than the maximum working pressure of the system). As a unloading valve, as a remote pressure regulator, as a high and low pressure multistage control valve, as a sequence valve, used to produce back pressure (string on the return oil circuit).
