The Youli YLMB52100 MB-5 Relief Valve Blanking Plug (Code SV) is designed for Youli MB-5 Monoblock Directional Control Valves when an integral inlet pressure relief valve is not required. The SV blanking plug installs in the MB-5 inlet relief cavity in place of an AG direct-acting or XAG pilot-operated relief valve, closing the relief valve cavity for hydraulic systems where pressure relief is provided elsewhere in the circuit. The Youli catalog specifically identifies YLMB52100 as the SV relief valve blanking plug for the MB-5 series.
Warning: The YLMB52100 is a blanking plug and does not provide pressure relief or overpressure protection. Use only in hydraulic systems with an appropriately sized and properly adjusted pressure relief device elsewhere in the circuit. Operating without adequate pressure protection can cause excessive system pressure, component failure, equipment damage, serious injury, or death. Always verify the hydraulic circuit and system requirements before replacing a relief valve with a blanking plug, and fully depressurize the hydraulic system before installation, removal, or service.
