Prevents Boom Droop: This valve securely locks the boom cylinder when the control lever is in neutral, preventing the boom from slowly lowering due to internal leakage or external loads. This is crucial for safety during lifting and when the machine is parked.
Ensures Load Holding: By locking the cylinder, it ensures the boom remains securely positioned during operation, preventing unintended movement or drooping.
