Suitable for JCB loader 3CX/4CX hydraulic pump solenoid valve 25-220804

1. Proportional solenoid valve (solenoid valve)

How it works:

All solenoid valve components are an electromagnetic coil in terms of the electrical part, that is, an inductor. When the inductor is given an electrical signal, the electromagnetic field generated by the current will make the valve core move and realize the change of the controlled parameters.

Quality identification:

Each solenoid has a fixed resistance value R, but this R cannot be "0" or

Is "∞", when R= "0" indicates an internal short circuit: when R= "∞" indicates an internal break

The Way; At the same time, the resistance of the coil to the housing cannot be "0". If the above conditions can be met

The solenoid valve can not work, it may be the signal input is wrong or the valve core hair card

Pressure compensation is a guarantee measure to improve the control performance of the valve. The load pressure after the valve port is introduced into the pressure compensation valve, and the pressure compensation valve adjusts the pressure in front of the valve port so that the pressure difference before and after the valve port is constant, so that the flow through the valve port according to the flow regulation characteristics of the throttle port is only related to the opening of the valve port, and is not affected by the load pressure.
