|---|---|
The 4V represents advanced electro-pneumatic control valve technology specifically designed for modern tipper truck hydraulic systems. This innovative internally pilot-actuated valve operates within a working pressure range of 0.15-0.8MPa with an optimized effective sectional area of 14-16mm², utilizing 40-micron filtered air for maximum reliability. The compact design combines engineering plastic and metal components, featuring top-mounted electrical controls and color-coded wiring for easy installation. As a sophisticated tipper truck control valve, it provides precise electro-pneumatic control over lifting, lowering, and stopping functions directly from the cabin. With IP65 protection rating and robust construction, this pneumatic control solution for dump trucks delivers exceptional performance in the most demanding mining, construction, and transportation applications, ensuring reliable operation in harsh environmental conditions.
Electro-Pilot: The driver no longer needs to physically push or pull long mechanical pneumatic levers in the cab. By sending an electrical signal (12V/24V) via an electric switch on the center console or a wireless remote control, a 4V solenoid coil can be instantly activated, releasing compressed air to drive the hydraulic lifting valve under the chassis.
High integration and high sensitivity (sliding column structure): The valve core adopts an industrial-grade sliding column structure , which has excellent sealing performance, extremely fast response speed (usually triggering action within 0.05 seconds), and low basic air pressure required for starting and braking.
Spring Return: For the lifting safety of dump trucks, the control valves are mostly equipped with mechanical spring return. In the event of an unexpected power outage or fuse blown in the truck's electrical circuit, the solenoid valve will immediately and automatically return to the safe stop or closed state under the action of the spring, preventing the cargo box from falling out of control.
Extended auxiliary functions (multi-path design): The 4V valve assembly can be freely combined via a manifold base. In addition to the lifting and lowering of the main circuit, the extra path can be perfectly used for automatic opening and closing of the pneumatic tailgate , side-tipping cargo box locking hooks , or lifting limit and speed limiting cylinders

Applications
Heavy Wheel Loaders & Excavators: Used to split fluid from the main piston pump, prioritizing smooth hydraulic power steering lines while routing the remaining flow to drive heavy boom, arm, and bucket actions.
Complex Sanitation & Garbage Compactors: Coordinates multiple automated steps. It precisely distributes pump power so the vehicle can lift heavy trash containers smoothly while running high-pressure compaction blades at a controlled, uniform speed.
Large Mobile Mining & Drilling Rigs: Feeds high-pressure oil to auxiliary stabilizer jacks while maintaining steady, non-pulsating rotation fluid on the primary drill motor line.
Dump Truck Electro-Pneumatic Control Valve 4V are typically packaged securely to prevent damage during transit. The packaging includes:
Protective Wrapping: To safeguard the pump from environmental damage.
Custom Crates: For larger, heavier pumps, ensuring safe handling.
Documentation: Includes installation, maintenance instructions, and warranty details.
Delivery time depends on the model, customizations, and location but typically ranges from 2 to 6 weeks from the order date.
A: This means that the pneumatic control pressure range of the valve is 0.6 to 1.2 MPa (equivalent to 6 - 12 Bar).
Compatibility: The air pressure of the standard brake system air tank of most medium and heavy-duty dump trucks (such as Shaanxi Automobile, Howo, Jiefang, etc.) is around 0.7-0.85 MPa , which is exactly within the optimal working pressure range of this valve. Therefore, it can be perfectly matched and the air source can be directly drawn from the truck's air brake system.
A: Direct-acting means that when you push or pull the operating handle, the mechanical structure of the handle directly and physically pushes the internal valve core to change the air path, without relying on any electrical signal or pilot air pressure to indirectly trigger it.
Advantages: The biggest advantage of this structure is its extremely rapid response and high reliability . As long as there is air in the cylinder, the air circuit will switch instantly with the driver's push of the lever, without any delay; at the same time, because complex intermediate control links are eliminated, the valve body structure is simpler, resulting in an extremely low failure rate in harsh working environments.
A: Dump trucks often operate in dusty construction sites or mines. If the vehicle's air dryer filter fails, the compressed air will contain sand, iron filings, or scale formed by water condensation.
Consequences: Hard particles larger than 40 micrometers can enter the valve body and scratch the surface of the direct-acting valve core during high-frequency pushing and pulling, or damage the internal rubber seals. This can cause air leakage and continuous micro-leakage in the valve body during shutdown or shutdown , ultimately leading to malfunction of the chassis hydraulic main valve or automatic slippage of the truck bed. Therefore, the air dryer filter element of the truck chassis must be replaced regularly .
A: The effective cross-sectional area determines the gas flow capacity (flow rate) . A range of 14-50 mm² indicates that the gas flow inside the valve is smooth.
Piping Recommendations: To ensure fast pneumatic signal transmission and prevent air blockage, it is recommended to use polyurethane (PU) or high- pressure nylon tubing with an outer diameter of 8mm (inner diameter approximately 5.5mm or 6mm) for the main air inlet (port 1) of this valve and the output ports (ports 21 and 22) leading to the chassis lifting valve. Using tubing that is too thin (e.g., with an outer diameter of 4mm) will restrict airflow, resulting in a slower response from the chassis hydraulic valves.
A: No, they are not contradictory. These are labels for two different pressure units and application locations.
Technical Explanation: 1.2 MPa (approximately 12.2 kgf/cm²) is the maximum safe pneumatic control signal pressure that the valve's internal structure and seals can withstand . 8.0 kgf/cm² (approximately 0.78 MPa) is the most recommended and typical continuous operating air pressure in a standard wet hydraulic system for dump trucks . This indicates that the valve has a high safety redundancy; even if the truck's air pump experiences a momentary surge in air pressure (e.g., reaching 1.0 MPa), the valve will not be damaged or burst.
