Disadvantages of hydraulic directional control valve

1.Regulation accuracy is limited.

4WEH Rexroth hydraulic solenoid valve is usually only switch two kinds of state, the valve core can only be in the two limit position, can not be adjusted continuously. A lot of new ideas to break through, but still in the trial stage, so the adjustment accuracy is also subject to certain restrictions.

2.Flow medium

The 4WEH Rexroth hydraulic solenoid valve on the media have high requirements for cleanliness, including granular media can not be applied, if must first filter out impurities.In addition, the viscous medium can not be applied, and the specific product is suitable for the medium viscosity range is relatively narrow. But some of these shortcomings can be avoided by selecting.
