Piston type electro-hydraulic valve instructions and acceptance:

1. When installing the electro-hydraulic valve, ensure its correct flow direction, and the flow direction sign is on the valve body. When THE NEW PIPELINE IS INSTALLED AND THE PIPELINE IS flushed, THE ELECTRO-HYDRAULIC valve must be removed first to avoid welding slag and debris remaining in the valve body and causing the electro-hydraulic valve to be closed loosely.

2. The dynamic viscosity of the working medium of the electro-hydraulic valve is less than or equal to 40 centipoise; Not easy to use wax media.

3. After receiving the equipment, the outer package should be checked immediately to see if there is any damage in the shipping process. Carefully remove the equipment from the packing case. Check whether any parts are damaged or missing. Check whether the packing list is consistent with the physical object, and whether it is consistent with the ordered model, specifications, and parameters.

4, electrical installation, first open the junction box, the middle of the wiring bar as shown in the figure: 2 kinds of wiring methods (1) normally open solenoid valve coil, a wire head connected to A column; Normally closed solenoid valve coil, a wire head connected with c column; In addition, the normally open and normally closed solenoid valve coil two wire heads and connect to b pillar. If DC 24V power supply is used, column A and C are connected to the positive pole of the power supply, and column B is connected to the negative pole of the power supply. If AC 220V power supply is used, column A and C are connected to live wire, and column B is connected to null wire. ② If the controller cannot control the two groups of electromagnetic coils, a and c can be connected to the output end of the controller with b respectively. Finally, tighten and press the nut to cover the junction box.
