Rexroth solenoid valves from Germany can be categorized into two types based on their function: on/off solenoid valves and proportional solenoid valves. 1) On/off solenoid valves function as switches; when current flows, the solenoid valve controls the opening and closing of the circuit or oil passage. 2) Proportional solenoid valves output pressure differently depending on the input current; changing the input current changes the output pressure, and they are commonly used in hydraulic systems.

Common Rexroth solenoid valve malfunctions include the solenoid valve failing to operate. Troubleshooting should begin with the following:

A Rexroth solenoid valve consists of an electromagnetic coil and a magnetic core, forming a valve body with one or more orifices. When the coil is energized or de-energized, the rotation of the magnetic core causes flow through the valve body or blocks it, thus changing the flow direction. The electromagnetic components of the solenoid valve consist of a stationary iron core, a moving iron core, and a coil; the valve body consists of a spool, a spool sleeve, and a spring base. The electromagnetic coil is directly mounted on the valve body, which is enclosed in a sealing tube,
forming a simple and compact assembly. Commonly used solenoid valves in our production include 2-position 2-way and 2-position 3-way valves. The term "two positions" refers to energized and de-energized states for a solenoid valve, and open and closed states for the valve it controls. When current flows through the coil, it generates an excitation effect, attracting the moving iron core to the fixed iron core. The moving iron core then drives the spool valve core and compresses the spring, changing the position of the spool valve core and thus changing the direction of the fluid. When the coil is de-energized, the spring force pushes the spool valve core back, causing the fluid to flow in its original direction.
Common faults of Rexroth solenoid valves include the solenoid valve not operating. The following troubleshooting steps should be taken:
(1) The solenoid N terminal is loose or the wire is detached. The solenoid valve will not be energized. Tighten the wire. (2) If the solenoid valve coil is burnt out, disconnect the solenoid valve wiring and measure with a multimeter. If it is open-circuited, the solenoid valve coil is burnt out. This can be caused by the coil being subjected to heat, leading to poor insulation and magnetic leakage, resulting in excessive current and burnout. Therefore, prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or too few coil turns and insufficient suction can also cause the coil to burn out.
(3) If the solenoid valve is stuck, the clearance between the valve sleeve and the valve core is very small. When mechanical impurities are introduced or the valve body is rusted, it can easily become stuck. The fundamental solution is to disassemble the solenoid valve, remove the N core and valve core sleeve, and clean them with CCI4 to ensure the valve core moves freely within the valve sleeve. During disassembly, pay attention to the assembly sequence of each component and the position of the external wiring to ensure correct reassembly and wiring. (5) If it is a pilot-operated solenoid valve, check if the differential pressure in the pipeline is too small. If the differential pressure is too small, the solenoid valve will not work properly. In this case, a direct-acting solenoid valve should be selected. If the differential pressure is too large, far exceeding the design value of the solenoid valve N, it will also not work properly. In this case, a high-performance solenoid valve should be used.
(6) If dirt in the pipeline blocks the small hole of the pilot valve, the pilot valve cannot open properly, and the main valve cannot open in time. The valve body can be disassembled, the dirt cleaned, and reassembled to work properly.
(7) In addition, solenoid valves are generally installed horizontally. If they are side-mounted, it may cause the valve to not close tightly, i.e., internal leakage. Side-mounting should be avoided as much as possible.
