Working principle of hydraulic solenoid valve

Bosch Rexroth 4WE10 hydraulic solenoid valve is a kind of automatic basic components which used to control the flow, belonging to the actuator.Directional hydraulic control valve used to control the direction of hydraulic flow, the plant’s mechanical devices are generally controlled by hydraulic cylinder, so it will be used in directional hydraulic control valve.
The Bosch Rexroth 4WE10 hydraulic solenoid valve has a closed cavity, in which the different position of the hole, each hole connecting different tubing.The middle of the cavity is the piston, the two sides are two magnets, which the magnet coil on the body will be attracted to the side, through the directional hydraulic valve to open or close the directional hydraulic control valve to open different oil drain hole.And into the hole is open, the hydraulic oil will enter a different row of tubing, and then through the pressure to promote the piston, the piston and the piston rod, the piston rod drives the mechanical device.Thus through the current control of an electromagnet to control the mechanical movement.

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.

Directional control valve selection

According to the requirements of the system to select the type of rexroth 4we6 hydraulic solenoid valve.For example,it should select one-way valve while the demand for oil flow can only flow in one direction, and can not reverse flow; if the required execution element is completed in a stop working cycle, the three bit reversing valve should be selected; if only needs two kinds of working state, namely the feed and return, then should use two position reversing valve, turn on or off the oil;If the actuator to complete the ‘fast forward, forward, rewind, stop’ the work cycle, or reciprocating frequent movement should normally be select the reversal valve to transform the oil flow direction.
You can also select rexroth 4we6 hydraulic solenoid valve according to the working status of the system and the characteristics of the valve. For example, the quality of the moving parts is small, the accuracy requirements are not high, the flow is less than 63 L / min, should choose the rexroth 4we6 hydraulic solenoid valve, because of the impact of this rexroth 4we6 hydraulic solenoid valve is large, so only the small flow allowed; If the moving parts quality, speed range is larger, and require to reverse smoothly, flow work energetically 63 L / rain, should use the electro-hydraulic valve; if the system has a lock loop, should choose the hydraulic control one-way valve with good sealing performance, but not the choice of sealing of the reversing valve.
