London Control Valve

London Control Valve

This is a genuine London replacement hydraulic solenoid valve assembly, part number MA-39790, used for mix and discharge control. The assembly is designed to be mounted on top of Eaton 54 Series hydraulic pumps. When activated, the solenoid valve directs hydraulic fluid to actuate a cylinder (such as MA-30226) which moves the pump's control arm, regulating the drum's rotation for charging or discharging concrete. This valve is a critical component for operators to control the mixer drum from the rear of the truck.
