6-37 How to check and repair the pressure maintaining valve?

Checking and repairing a pressure maintaining valve involves observing pressure in a loaded state, replacing worn O-rings and sealing rings, cleaning, and reassembling.

Answer: The pressure maintaining valve is checked by putting the machine in a loaded state, opening the pipeline or the drain valve on the pipeline. When the drain valve discharges pressurized air, observe the pressure before separation. This is the opening value of the pressure maintaining valve. If it is around 0.45MPa, it means that the operation is normal. The maintenance method is as follows:

(1) Loosen the spring pressure cap and be careful of the elastic force in the valve.

(2) Remove the spring pressure cap.

(3) Check the condition of the O-ring on the piston. If it is worn, replace it.

(4) Check the sealing ring. If it is damaged, replace it.

(5) Clean it with a cleaning agent and lubricate it with high-temperature grease. Reinstall it in the opposite direction of disassembly.

However, those with sealed components, including motors, controllers, and connectors, can also be operated outdoors. Performance IC forklifts tend to be utilized in heavy-duty applications, such as brick and lumber yards, where larger capacity and performance is required to move the heavy loads.
