Things to Consider During Installation and Replacement
During the disassembly and installation stages of valve blocks, it is critically important to completely depressurize the hydraulic line and clean the connection surfaces to prevent oil leaks. During installation, make sure that the socket connections are made correctly and the in-line seals are not deformed. You can check the label information on your machine's existing valve block to clarify the compatibility of this component with the code 20Y6041621.
