READ MOREWhat are the faults of single-head solenoid reversing valve?
Common faults of single-head electromagnetic reversing valves mainly include unreliable commutation, coil failure, leakage problems, shock and vibration, and installation and assembly problems, as follows: Unreliable commutation or inability to commutate: Electromagnet problems: Burned out electromagnet coil, insufficient electromagnet driving force or magnetic leakage, electrical circuit failure, etc., may cause the electromagnet to fail to work properly, thereby affecting commutation. For example, a coil short circuit or open circuit may be caused by coil quality problems, excessive power supply voltage, repeated shocks, or excessive mechanical vibration. Pilot solenoid valve failure: the valve core and valve body hole are stuck, the spring is bent sideways, etc., which may also lead to unreliable commutation. This is usually caused by poor geometric accuracy of the parts, tight fit between the valve core and the valve hole, or excessively dirty oil. The main valve core is stuck: The geometric accuracy of the valve core and the valve body is poor, the valve core and the valve hole are too tight, there are burrs on the valve core surface, or there is no oil in the control oil line, etc., which may cause the main valve core to be stuck, thus affecting the direction change. Other factors: if

READ MOREWorking principle of 4WE10 high pressure solenoid reversing valve
The working principle of 4WE10 high-pressure solenoid directional valve is as follows: Basic structure: 4WE10 high-pressure solenoid directional valve is mainly composed of valve body, valve core, electromagnet and return spring. There are multiple oil ports in the valve body, and the valve core can move in the valve body to change the connection status of the oil ports. Electromagnetic control: energized state: When the electromagnet is energized, electromagnetic force is generated to attract the valve core to move, overcome the resistance of the return spring, and make the valve core reach the designated position. At this time, specific oil ports are connected, and hydraulic oil can flow through these ports, thereby changing the direction of the oil path of the hydraulic system. Power-off state: When the electromagnet is powered off, the electromagnetic force disappears, and the return spring pushes the valve core back to its initial position, closing the previously connected oil port and restoring the valve's initial state. Oil circuit switching: By controlling the power on and off of the electromagnet, the valve core moves back and forth in the valve body to achieve switching between different oil ports and control the flow direction of hydraulic oil. This makes the actuators in the hydraulic system (such as hydraulic cylinders

READ MOREApplication range of ZDB10V superimposed relief valve
As a pilot pressure control valve, the ZDB10V superimposed relief valve achieves multi-stage pressure regulation and stable control through modular design. It is widely used in engineering machinery, industrial equipment, shipbuilding, automation equipment, hydraulic testing systems and other fields. The following is its specific application scope and technical advantages: 1. Typical equipment in core application fields of engineering machinery: hydraulic circuits such as excavators, cranes, loaders, etc. Function: As the main safety valve to prevent system overpressure, it also adapts to different working conditions (such as excavation, walking, and lifting) through multi-stage pressure adjustment. Advantages: The superimposed structure saves installation space, responds quickly to pressure changes, and avoids equipment damage due to pressure shock. Typical equipment for industrial automation equipment: injection molding machines, die-casting machines, hydraulic presses and other precision manufacturing equipment. Function: Provide stable pressure during mold closing, injection, pressure holding and other stages to ensure product molding quality. Advantages: Supports multi-level pressure switching, adapts to complex process flows, and reduces energy loss.
