Designed to ensure pressure regulation in the hydraulic systems of Komatsu WA series heavy machinery, the part coded 423-43-37650 supports the stability of system flow control. Having the original part number 423-43-37650 (or in its space-free format 4234337650), this charge valve relief directly fits the corresponding lines of WA380-6, WA430-6, WA470-6, WA480-6, and WA500-7 model loaders.
Protecting the safety of the hydraulic circuit against excessive pressure fluctuations, this valve component is manufactured to fit mounting housings perfectly. While maintaining the pressure balance between the hydraulic charge pump and related control blocks, it contributes to the efficient operation of the system by regulating the flow direction and amount of hydraulic oil. During removal and installation processes, paying attention to the cleanliness of threaded connection surfaces and sealing elements is important for the continuity of system performance.
Before replacement, verify compatibility by comparing your machine's serial number, relevant hydraulic circuit diagrams, and the 423-43-37650 part code with your own chassis bulletin.
