Rexroth solenoid valve stuck: The clearance between the solenoid valve spool and the valve core is very small (less than 0.008mm), and they are usually assembled as a single piece. When mechanical impurities are introduced or there is insufficient lubricating oil, it is easy for it to get stuck. A temporary fix is to insert a steel wire through the small hole at the head to make it spring back. The fundamental solution is to disassemble the solenoid valve, remove the valve 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. Also check if the lubricator spray hole is blocked and if there is sufficient lubricating oil.

Rexroth solenoid valves have a sealed chamber with through-holes at different positions, each connecting to a different oil pipe. Inside the chamber is a piston, flanked by two electromagnets. When the coil of one electromagnet is energized, the valve body is attracted to that side. Controlling the movement of the valve body opens or closes different drain holes. The inlet hole is always open, allowing hydraulic oil to enter different drain pipes. The oil pressure then pushes the piston in the cylinder, which in turn moves the piston rod, which in turn drives the mechanical device. Thus, controlling the flow of current to the electromagnets controls the mechanical movement.
Rexroth Solenoid Valve Selection Criteria:
1. Selecting the solenoid valve based on pipeline parameters: Nominal diameter (DN), connection type
1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements.
2) For connection type, generally, >DN50 requires a flange connection; ≤DN50 can be selected freely according to user needs.
2. Selecting the solenoid valve based on fluid parameters: Material, temperature group
1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended.
2) High-temperature fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves should be chosen.
3) Fluid state: Valves can be gaseous, liquid, or mixed, especially for diameters greater than DN25, which must be clearly distinguished.
4) Fluid viscosity: Generally, below 50 cSt, any valve can be selected; if it exceeds this value, a high-viscosity solenoid valve should be selected. 3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structure
1) Nominal Pressure: This parameter has the same meaning as other general-purpose valves, determined by the nominal pressure of the pipeline.
2) Working Pressure: If the working pressure is low, a direct-acting or step-direct-acting principle must be selected. For a minimum working pressure difference of 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected.
4. Electrical Selection: AC220V and DC24V voltage specifications should be prioritized for convenience.
5. Selecting Based on Continuous Working Time: Normally Closed, Normally Open, or Continuously Energized
1) When the solenoid valve needs to be open for a long time, and the continuous time is longer than the closing time, a normally open type should be selected.
2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected.
3) However, for some safety protection applications, such as furnace and kiln flame monitoring, normally open valves cannot be selected; a continuously energized type should be chosen. 6. Select auxiliary functions according to environmental requirements: explosion-proof, backflow preventer, manual operation, waterproof mist, water spray, and submersible.
