The working principle of the 2 way hydraulic solenoid valve is as follows: 1,2 air inlet; 4,5 exhaust; when the coil is energised, the static iron core generates electromagnetic force, which causes the pilot valve to operate, and compressed air enters the pilot piston of the valve through the air circuit to activate the piston, and the sealing surface opens up the channel in the middle of the piston, so that 1,4 air inlet, and 2,3 exhaust; when the power is cut off, the pilot valve resets under the action of the spring, and restores the valve to its original state.
Extended information:
2 way hydraulic solenoid valve composition structure and working principle:
1, the solenoid valve composition structure: by the electrical part and pneumatic actuator part;
2, the working principle of the solenoid valve:
When we charge the electrical part of the solenoid valve, the electromagnetic coil produces electromagnetic force that lifts and closes the sealing air hole. This allows compressed air to enter the pilot valve, causing it to operate. If power fails, the electromagnetic force disappears, and the valve action reverses.
Solenoid valve pneumatic actuating part of the pilot valve piston and the main piston rod at the other end of the common action of the spring movement, to complete the two-position five-way switching.
A two-position five-way solenoid valve is used to control fluid automation and is a basic component of the actuator. It is not limited to hydraulic systems but also applies to pneumatic systems. Solenoid valves are used to control the direction of hydraulic flow. Factory mechanisms are generally controlled by hydraulic cylinders. Therefore, solenoid valves are used in these systems.
