Excavator accessories 180584A1 solenoid valve for MX80C MX90C hydraulic valve

Solenoid valve structure principle

1. action express, small power, lightweight appearance

    The response time of the solenoid valve can be as short as a few milliseconds, and even the pilot-operated solenoid valve can be controlled within tens of milliseconds. Because of its own loop, it is more responsive than other automatic control valves. Properly designed solenoid valve coil power consumption is very low, is energy-saving products; It can also be done only to trigger the action, automatically maintain the valve position, usually no power consumption. Solenoid valve size is small, not only save space, but also lightweight and beautiful.

2.  the adjustment accuracy is limited, the applicable medium is limited

   The solenoid valve usually has only two states of switch, and the spool can only be in two limit positions, and cannot be adjusted continuously, so the adjustment accuracy is also limited.

    The solenoid valve has high requirements for the cleanliness of the medium, and the medium containing particles cannot be applied, such as impurities must be filtered first. In addition, viscous media cannot be applied, and the medium viscosity range suitable for specific products is relatively narrow.

  3. the external leakage is blocked, the internal leakage is easy to control, and the use is safe

Internal and external leakage is an element that endangers safety. Other automatic control valves usually extend the stem, and the rotation or movement of the spool is controlled by an electric, pneumatic, and hydraulic actuator. It is necessary to solve the external leakage problem of long-term action valve stem dynamic seal; Only the solenoid valve is the completion of the iron core sealed in the magnetic insulation tube of the electric control valve, and there is no dynamic seal, so the external leakage is easy to block. Electric valve torque control is not easy, easy to produce internal leakage, and even pull the stem head; The structure of the solenoid valve is easy to control the internal leakage until it is reduced to zero. Therefore, the solenoid valve is particularly safe to use, especially for corrosive, toxic or high and low temperature media.
