The working principle of the electro-hydraulic reversing valve
When two solenoid valve coils have power on, the balance hole loop is closed, the discharging hole loop is opened, discharging pressure from the cavity on the piston, the piston moves upward and the the valve door is opened. Otherwise, the piston downward, the valve closed. In the process of opening and closing the valve, and the flow rate (velocity) signal plug position signal transmitted to the computer, to send out the corresponding instruction after computer processing and control of two electromagnetic pilot valve, power status, making changes on the inferior vena hydraulic differential piston so as to control the piston in the open height the control system for the pipe flow of medium.
The instructions of the electro-hydraulic reversing valve
1. The product can be installed anywhere, giving priority to the horizontal position.
2. The medium used in the hydraulic system must be filtered, the filtration precision is at least 20 ¦Ìm.
3. Please select the set screw according to the parameters listed in the sample.
4. The surface connected to the valve,its roughness request is Ra0.8, and the flatness requirement is 0.01/100 mm
