Separate
solenoid valves and hydraulic valves:
Structure: The solenoid valve and the hydraulic valve are separated, that is, the solenoid valve exists alone, and the opening and closing of the hydraulic valve is controlled by electromagnetic force.
Working principle: Through the action of electromagnetic force, the piston or valve core of the hydraulic valve is moved, thereby changing the state of the fluid channel.
Advantages: Easy to install and maintain, different valve core and solenoid valve combinations can be selected according to specific needs.
Disadvantages: Large space occupied, complex pipelines, and high installation costs.
Integrated solenoid and hydraulic valves:
Structure: Integrated design of solenoid valve and hydraulic valve, solenoid valve and hydraulic valve form a whole.
Working principle: The solenoid valve controls the position of the internal valve core through electromagnetic force, thereby directly controlling the flow of hydraulic oil.
Advantages: compact structure, easy installation, simple pipeline, small size and high integration.
Disadvantages: Inconvenient maintenance, high overall replacement cost when a fault occurs, and not conducive to the replacement of individual components.
