Product Description

The German HYDAC Herdek solenoid valve is a step action direct pilot solenoid valve, which can be divided into normally closed solenoid valve and normally open solenoid valve according to the different opening and closing states when the power is off. HYDAC Hedek normally closed solenoid valve, after the line is powered, the armature under the action of electromagnetic force first drive the adverb valve plug, the fluid on the main valve cup flows through the auxiliary valve, reducing the pressure on the main valve cup, when the pressure on the main valve cup is reduced to a certain value, the armature drives the main valve cup, and the use of pressure difference to make the main valve cup open, the medium circulation. When the wire is powered off, the electromagnetic force disappears and the armature resets due to its own weight.

At the same time, relying on the medium pressure, the main and secondary valves can be tightly closed, normally open the solenoid valve, after the line is energized due to the suction action, the moving iron core moves down, the auxiliary valve plug is pressed down, the auxiliary valve is closed, the pressure in the main valve cup rises, when the pressure rises to a certain value, the upper and lower pressure difference of the main valve cup is the same, due to the electromagnetic force, the moving iron core pushes the main valve cup down, compacts the main valve seat, and the valve is closed. When the line power off, the electromagnetic suction is zero, the auxiliary valve plug and the moving iron Bi lift up due to the spring action, the auxiliary valve is opened, and the fluid on the main valve cup flows away through the auxiliary valve, reducing the pressure on the main valve cup. When the pressure on the main valve cup is reduced to a certain value, the pressure difference is used to push the main valve cup up, the main valve is opened, and the medium circulates.
