1. Prepare tools: To disassemble the proportional valve, you need to use wrenches, torque wrenches, hexagonal wrenches and other tools, and you also need to prepare detergents, lubricants and other items.
2, disassemble the proportional valve: first of all, you need to remove the hydraulic retarder tubing and wires, and then use a wrench to remove the proportional valve nut, the proportional valve from the hydraulic retarder. During the disassembly process, you need to be careful not to damage the proportional valve and other parts of the hydrodynamic retarder.
3, cleaning and inspection: after removing the proportional valve, you need to clean the proportional valve and the hydraulic cylinder with a cleaner, and check the proportional valve's sealing, operating flexibility, and the surface condition and so on whether it is normal.
4, replacement or repair: the proportional valve failure or need to be replaced, can be repaired or replaced as needed. When replacing or repairing, you need to use the correct parts and tools and follow the operating instructions.
5, install the proportional valve: after the replacement or repair is completed, you need to reinstall the proportional valve to the hydrodynamic retarder, and use a torque wrench in accordance with the specified torque for tightening. Then reconnect the oil pipes and wires, and test and debug. The Voith Retarder Proportional Valve is one of the important components of the Retarder, and its function is to control the output flow and pressure of the Retarder in order to realize the retardation and load protection of the mechanical drive system.
