It is essential to install filters before the hydraulic control valve and ensure they are easily accessible for drainage.
The hydraulic control valve features a self-lubricating body, eliminating the need for additional lubrication. If any internal components of the main valve are damaged, follow the steps below for proper disassembly. (Note: common damages include the diaphragm and O-rings.)
1. Begin by closing both the upstream and downstream soft-seal gate valves of the main hydraulic control valve.
2. Loosen the pipe joint screws on the valve cover to release any built-up pressure inside the system.
3. Remove all screws, including those securing the copper tubes in the control lines.
4. Carefully take off the valve cover and spring assembly.
5. Extract the shaft core, diaphragm, piston, and other internal parts, making sure not to damage the diaphragm during the process.
6. After removing the components, inspect the diaphragm and O-ring for signs of wear or damage. If no damage is found, avoid unnecessary replacement of internal parts.
7. If the diaphragm or O-ring is damaged, loosen the nut on the shaft core, carefully remove the faulty component, and replace it with a new one.
8. Thoroughly examine the internal valve seat and shaft core for any damage or debris. Clean the interior of the main valve if necessary.
9. Reassemble the replaced parts in the reverse order of disassembly, ensuring the valve moves smoothly without jamming.
Always make sure to follow safety procedures when working with hydraulic systems. Proper maintenance and timely repairs can significantly extend the life of the hydraulic control valve and prevent unexpected failures. Regular inspections are recommended to catch minor issues before they escalate into major problems. If you're unsure about any step, consult a professional technician or refer to the manufacturer's manual for detailed guidance.
