Hyva JQF34-A 14750667H Dump Truck Standard Air Control Valve Lift Valve

Product Description:

JQF34A is a three position four-way manual directional valve, typically used as the main control valve for dump truck hydraulic systems. It controls the flow of high-pressure hydraulic oil through the control lever (manual or electrically controlled pneumatic) inside the cab, thereby driving the lifting cylinder to complete various actions.

Its design is known for its high strength, high reliability, and good sealing, which can adapt to the harsh working environment of construction vehicles. High performance: capable of handling high working pressure and large flow to meet the lifting needs of heavy-duty dump trucks.

High reliability: Made of high-quality materials and precision machining, the valve core and body are durable and wear-resistant, with excellent internal sealing performance and low leakage.

Smooth operation: The optimized oil passage design ensures smooth lifting and lowering of the cargo box, reducing impact.

Safety protection: The built-in safety valve (overflow valve) prevents excessive system pressure and protects components such as oil pumps, oil cylinders, and pipelines.

Floating function: A dedicated floating position is an essential function for dump truck operating conditions, protecting equipment and facilitating operations.

Modularity and compatibility: Designed to perfectly match HYVA's oil pumps, cylinders, and other components, forming a complete hydraulic system. The interface standard also facilitates installation and replacement on similar vehicle models.

Applications:

The dump truck/dump truck controls involve the lifting, lowering, mid-stop, and floating of the cargo box. These functions demand high reliability and a large flow rate to handle heavy loads and harsh working conditions.

When it comes to the garbage compactor, it's responsible for controlling the compression mechanism circulation, filling device lifting, garbage bin lifting, and other related operations. These actions can be more complex, necessitating valves that can respond sensitively and have excellent sealing performance.

Truck-mounted cranes or lifting transport vehicles are often utilized to support the extension and retraction of support legs or specific hydraulic functions of the crane.

Special devices are used to control sanitation vehicles like sprinkler trucks, suction trucks, and other equipment.

In the case of agricultural and mining machinery, such as large-scale agricultural dump trucks and mining wide-body dump trucks, they face extreme working conditions that demand valves with extremely high pressure resistance and durability.

For special operation platforms controlling the takeoff and landing of maintenance platforms and lifting platforms, stability and safety locking functions are imperative.
