Introduction to DC solenoid valves: Solenoid valves are used in hydraulic systems to control the flow of fluid, either opening or closing the circuit. They typically have a valve core that slides under the electromagnetic force of a coil.

The number of positions the valve core holds determines the valve's port number.

The number of ports on the valve body determines the valve's passage number. Rexroth solenoid valve specifications:

• The product can be installed in any position, but a horizontal position is preferred.
• The medium used in the hydraulic system must be filtered, with a filtration accuracy of at least 20μm.
• Please select the fixing screws according to the parameters listed in the sample.
• The surface connected to the valve must have a surface roughness of Ra0.8 and a flatness of 0.01/100mm. Rexroth solenoid valve working principle: When both solenoid valve coils are energized, the balance orifice circuit is closed, the venting orifice circuit is opened, the upper chamber of the piston is depressurized, the piston moves upward, and the valve opens. Conversely, the piston moves downward, and the valve closes. During valve opening and closing, flow rate (velocity) signals and valve plug position signals can be transmitted to the computer. After processing, the computer issues corresponding commands to control the on/off state of the two solenoid pilot valves, causing changes in the hydraulic pressure difference between the upper and lower chambers of the piston, thereby controlling the piston at the required opening height and achieving control of the pipeline medium flow rate.

• Rexroth 4WEH.. type directional valve Model 4WEH.. type directional valve WEH type directional valve is a type of electro-hydraulic operated directional slide valve. They are used to control the opening, stopping and direction of fluid flow. The main components of this type of valve include valve body
• main control valve core
• one or two return springs (3.1) and (3.2), pilot valve
• with one or two electromagnets: electromagnet "a" (5.1), electromagnet "b" (5.2). The main valve core is held in the neutral or initial position by spring or hydraulic pressure. In the initial position, the two spring chambers
• and
• are connected to the unpressurized tank via the pilot valve. Oil is supplied to the pilot valve
• via the control oil circuit
• . The control oil can be supplied internally or externally (external supply port X). When the pilot valve is operated, such as when the electromagnet "a" is energized, the pilot slide valve
• moves to the left, so the spring chamber
• receives pilot oil pressure while the spring chamber
• remains unpressurized. The pilot pressure is applied to the left end of the main valve core and overcomes the spring force (3.1), resulting in the connection of P to B and A to T of the main valve. When the electromagnet is de-energized, the pilot valve returns to the initial position (except for slide valves with positioning mechanisms), and the spring chamber
• is unloaded to the tank. The control oil is discharged from the spring chamber through the pilot valve into port Y. The control oil can be supplied internally or externally, and the return oil can be externally via port Y. Emergency manual operation
• is selectable.
• Rexroth LC.. type two-way cartridge valve. The Rexroth two-way cartridge valve is designed as a plug-in structure for use in an integrated block. The main valve assembly with ports A and B is inserted into the socket on the control block with dimensions conforming to the DIN ISO 7368 standard and sealed with a control cover. In most cases, the cover serves as a connection between the control side of the main assembly valve and the pilot valve. A suitable pilot valve is used to control the main valve, and the main valve assembly can perform pressure, direction, or throttling functions, or a combination of these functions. The flow rate changes of valves and actuators of different diameters need to be matched to achieve a special economic structure design. If the main valve assembly can perform more than one function, a special economic structure can be achieved. The basic components of a Rexroth 2-way cartridge valve with directional function mainly include a control cover
• and a insert
• . The control cover contains a control hole, a stroke limiter (optional depending on functional requirements), and a hydraulically controlled directional seat valve or shuttle valve. Additionally, a directional spool valve or directional seat valve can be mounted on top of the control cover. Description: The actuation of the Rexroth 2-way cartridge valve depends on pressure. Therefore, for valve actuation, there are three important pressure-bearing areas: A1, A2, and A3. The valve seat area (A1) is the highest standard, and the annular area (A2) is 7% or 50% of the area (A1) depending on the type. Therefore, the area ratio A1:A2 is either 14, 3:1, or 2:1. A2. Because the A1:A2 area ratio is different, the annular area A2 is also different. When the valve seat area A1 is the highest standard, the area A3 may be 107% or 150%. Basic application of Rexroth cartridge valves: Areas A1 and A2 act in the valve opening direction. Area A3 and the spring act in the valve closing direction. The effective direction of the combined force (opening force or closing force) determines the opening and closing state of the two-way cartridge valve. The flow direction of the two-way cartridge valve can be from A to B or from B to A. If the control pressure acting on area A3 comes from port B or the control oil is supplied externally, port A is closed and there is no leakage.
