Common faults of REXROTH solenoid valves include the solenoid valve not operating. The following troubleshooting methods should be used:

(1) Loose or detached solenoid N-connection. The solenoid valve will not receive power. Tighten the wire.

(2) Burned-out solenoid coil. Disconnect the solenoid valve wiring and measure with a multimeter. If an open circuit is detected, the solenoid coil is burnt out. This can be caused by the coil being subjected to NJ (non-electric shock), resulting in poor insulation and magnetic leakage, leading to excessive current and burnout. Therefore, prevent rainwater from entering the solenoid valve. Additionally, an overly stiff spring, excessive reaction force, or insufficient coil turns can also cause the coil to burn out.

(3) Solenoid valve jamming. The clearance between the valve sleeve and valve core of the solenoid valve is very small. When mechanical impurities are introduced or the valve body is rusted, it can easily jam. 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 location of 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 N, it will also not work properly. In this case, a high-performance solenoid valve should be used.

(5) 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 ensure normal operation.

(6) 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. A REXROTH solenoid valve consists of a solenoid coil and a magnetic core, and a valve body containing one or more orifices. When the coil is energized or de-energized, the rotation of the magnetic core causes fluid to flow through the valve body or be cut off, thus changing the direction of fluid flow. The electromagnetic components of a solenoid valve consist of a fixed iron core, a moving iron core, and a coil; the valve body consists of a spool, a spool sleeve, and a spring base. The solenoid 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 production include 2-position 3-way, 2-position 4-way, and 2-position 5-way valves. Here, let's first explain the meaning of "2-position": for a solenoid valve, it means energized and de-energized; for the valve it controls, it means open and closed.

Rexroth solenoid valves are electromagnetically controlled industrial devices, fundamental components of automation systems used to control fluids. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Common types include check valves, safety valves, directional control valves, and speed control valves.
