What is the function of the relief valve used by the cutting machine?
Dec 07, 2018

The relief valve is a hydraulic pressure control valve, which mainly plays the role of constant pressure overflow, voltage regulation, system unloading and safety protection in the hydraulic equipment of the cutting machine. In the assembly or use of the relief valve, due to the damage of the O-ring, the combined seal, or the looseness of the mounting screws and fittings, it may cause undue external leakage. 

If the cone valve or the main spool is worn too much, or the sealing surface is not well contacted, it will cause excessive internal leakage and even affect normal operation.
