Product details
"Joystick and Hydraulic Cartridge Relief Valve":
 
Joystick
 
The joystick is a device used in heavy-duty machinery such as excavators to control various movements, such as the boom, arm, bucket operations, and the machine's rotation. It is typically located within the cab, where the operator can send signals by moving the joystick to control the valves in the hydraulic system, thereby achieving precise control over the excavator's movements. The joystick design allows operators to move heavier components with minimal effort, enhancing work efficiency and operator comfort.
 
Hydraulic Cartridge Relief Valve
 
The hydraulic cartridge relief valve is a crucial safety device in hydraulic systems. When the pressure within the system exceeds a preset value, the relief valve automatically opens to release excess pressure, protecting the system and equipment from damage. This relief valve adopts a cartridge design, making it convenient to install in the hydraulic circuit of the system, occupying minimal space and facilitating maintenance and replacement.
 
The working principle of the hydraulic cartridge relief valve is based on pressure control. When the system pressure rises to the set value, the valve spool is subjected to pressure and moves, thereby opening the valve and allowing some hydraulic oil to flow back to the reservoir or the low-pressure part of the system, reducing the system pressure. Once the system pressure drops below the set value, the valve automatically closes, continuing to maintain the normal operation of the system.
 
In addition, hydraulic cartridge relief valves have a wide range of adjustment, fast response times, ease of use, and simple maintenance. They can be set with different opening and closing pressure values according to actual needs to adapt to different application scenarios. At the same time, due to their compact structure and easy installation, they are widely used in various hydraulic systems.
 
In summary, both the joystick and the hydraulic cartridge relief valve are indispensable components in heavy-duty machinery such as excavators. They work together to achieve precise control over mechanical movements and pressure protection, improving work efficiency and safety.
