Relief Of Hydraulic Valve

 The working pressure grade is normal pressure, which conforms to the normal pressure conditions of most construction machinery hydraulic systems. It can be directly installed and used without additional pressure adaptation, with a wide range of adaptation, which reduces the threshold for customers to use and ensures the pressure stability of the hydraulic system. Main points of installation and replacement (1) Preparation for replacement Shut down the hydraulic system and release the internal pressure of the system to avoid safety accidents during replacement; Prepare necessary tools, including wrenches, filter element wrenches, Allen wrenches, cleaning tools, etc. (II) Removal of old valves Dismantle the oil pipe and connector on the overflow valve to reserve space for subsequent operation; Loosen the nut or bolt on the overflow valve with a wrench or socket wrench; Take out the old relief valve from the hydraulic system, and be careful in operation to avoid damaging other system components. (3) Cleaning and inspection Clean the overflow valve with the specified cleaning agent to remove dirt and deposits on the surface of the valve body. Corrosive acid-base solutions are strictly prohibited. Check the sealing surface of the overflow valve. If there is any damage such as wear and crack, it is necessary to
