| Part Category | Key Functions |
| Multi-way valve / Electromagnetic directional valve | Core control components are used to switch the hydraulic oil circuit and drive different actuators. For example, the 3 series pilot electro-hydraulic multi-way valve, the Dipma DS3 series solenoid valve, etc., enable precise control of the boom's swing and elevation. |
| Balance valve | It is an external control and internal release type one-way sequential valve, commonly used in the hydraulic cylinders of boom and legs, serving the functions of load retention, preventing drop, and energy saving and consumption reduction. The new "green valve" design can utilize the gravitational descent to reduce energy consumption. |
| Check valve / Throttle valve | Installed at the end of the hydraulic pipeline, it is used for manually or automatically cutting off the oil flow, facilitating maintenance or preventing backflow. |
| Other auxiliary valves | Including electromagnetic valve coils, safety valves, handbrake valves, etc., they are used for specific functions such as air conditioning control, braking systems, etc. |
| Actuators/Motors | Located between the hopper and the conveying cylinder, it is responsible for switching the intake and output paths of the concrete. It is the core component of the pumping system. |
| S-shaped valve (S valve) | The most widely used type currently is one with an S-shaped valve body. It achieves the alternation of material suction and pumping by swinging the oil cylinder left and right, connecting the two concrete cylinders on either side. Its advantages include high pumping pressure, long conveying distance, and good sealing performance. However, it has a small bending radius and is prone to clogging in low-flow concrete. |
| Gate valve | This was commonly seen in early concrete pump trucks. It switched the flow channels through the up-and-down or oblique movement of the gate plate. The structure was simple, but the sealing performance was poor. It was not suitable for high-pressure and long-distance pumping and is now rarely used in modern pump trucks. |
