12/24V Fuel Solenoid Valve 6630546 6632196 For 843 853 1213 2000

The main function of excavator solenoid valve is to control the direction, flow rate and speed of fluid flow. As the basic component of automation, solenoid valve controls the movement of valve core through electromagnetic force, thus changing the position of fluid channel and realizing accurate control of fluid.
one

Specific function
Control the direction of fluid: the solenoid valve can switch the direction of fluid flow, for example, control the direction of hydraulic oil in an excavator to achieve different actions and functions.
one
Adjust the flow and speed: By controlling the position of the valve core, the solenoid valve can adjust the flow and speed of the fluid, thus controlling the running speed and strength of the equipment.
one
Safety protection: In some cases, the solenoid valve can also be used for safety protection, such as cutting off the fluid supply when the pressure is too high or the system is abnormal to prevent the equipment from being damaged.

Common types and application scenarios
One-way valve: allows fluid to flow in one direction, and is often used to prevent fluid from flowing backwards.
Safety valve: automatically open when the system pressure is too high, release the pressure and protect the system.
Directional control valve: control the flow direction of fluid and realize different operation actions.
Speed regulating valve: regulates the flow and speed of fluid and controls the running speed of equipment.
Safety locking solenoid valve: when the locking lever is lowered, it is energized to switch the oil circuit to realize the safety locking function.

Troubleshooting and maintenance methods
Check the power supply: ensure that the power supply of the solenoid valve is normal and there is no short circuit or open circuit.
Cleaning and maintenance: clean the solenoid valve and its surrounding environment regularly to prevent impurities from blocking the valve core.
Check the spool and spring: make sure that the spool moves smoothly and the spring works normally.
System pressure test: check the system pressure regularly to ensure that it is within the normal range.
Professional maintenance: When encountering complex faults, it is recommended to contact professional maintenance personnel for diagnosis and repair.
