Q23 Light Truck Self Unloading Directional Valve  

Overview

Suitable for agricultural light truck dump truck hydraulic system, can match double multistage cylinder or single rod piston cylinder, lift and drop. Internal safety relief valve, system pressure can be set. Can use the control valve, remote gas control reversing control.

Features and Benefits

  • This product can be equipped with electronic control integrated system to achieve dual-use electrical control andremote control, more safe and flexible!

  • The valve core is equipped with chrome plating treatment, which greatly improves the surface hardness and wearresistance of the valve core.

  • The valve body is made of vermicular graphite cast iron RT450 material, with high wear resistance, high temperatureand high pressure resistance. Even in high temperature and high pressure environment can work stably, the valve hole isnot easy to deform.

  • The rubber ring is made of fuorine rubber material, which is resistant to high temperature and chemical corrosion, andhas good anti-aging and high-pressure performance, and the permeability is also very low, even in very harsh workingconditions, it still has very good wear resistance.S. Safety relief valve after strict pressure test, accurate opening and closing, with lead seal does not allow privatepressure regulation.

Applications


  • 1. Light & Medium-Duty Dump Trucks

    Acts as the cabin controller (joystick/lever) for the driver.

    Manages the lifting, holding, fast-lowering, and slow-lowering of the tipper bed.

  • 2. Specialized & Sanitation Vehicles

    Controls the tipping and cargo-unloading mechanisms in garbage trucks, hook-lift trucks, and municipal maintenance vehicles.

  • 3. Agricultural Transport Equipment

    Used in farm tippers, self-unloading grain trailers, and small utility transport vehicles to safely dump heavy crops or soil.

  • 4. Industrial Air Compressors (Specific Solenoid Variants)

    Used as the loading/unloading solenoid valve in rotary screw air compressors to regulate intake air and power-saving idle cycles.

Packaging & Delivery

Shipping Methods

Q23 valves 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.


Q23 Light Truck Self Unloading Directional Valve  FAQ:

1. What is the main function of the Q23 valve in a dump truck?
  • It acts as a pneumatic control switch inside the cabin. It directs compressed air from the vehicle's air tank to shift the main hydraulic proportional valve (PT valve), allowing the driver to control the lifting, holding, and lowering of the self-unloading truck bed.

2. Why does the truck bed drop too fast, and how does the Q23 valve help?
  • Fast drops are dangerous and can damage the chassis. Most Q23 valves (like the Q23-15Y) feature a proportional slow-descent mechanism. When you push the lever slightly into the down position, it restricts the air exhaust flow, causing the main hydraulic valve to open only partially for a smooth, slow drop.


3. What causes air hissing or leaking from the Q23 valve ports?
  • Air leaks are usually caused by worn-out internal rubber O-rings or moisture/dirt entry from the truck's air lines. If air leaks constantly when you try to lift the bed, the internal seals must be replaced, or the entire valve assembly needs to be swapped out.


4. Can a Q23 valve be used on an electric dump truck without an air brake system?
  •  No. Standard Q23 valves are pneumatic (air-operated) and require a steady auxiliary compressed air supply (0.6–1.2 MPa). If your light truck does not have an air compressor tank (common in small electric or gasoline light trucks), you must use a direct electric solenoid hydraulic valve instead.

5. What is the difference between the manual lever Q23 valve and the solenoid Q23 valve?
  • The manual lever version is a mechanical joystick installed next to the driver's seat, directly routing air lines into the cab. The solenoid version (e.g., Q23DA) is an electronic air valve mounted on the chassis; it is controlled remotely via an electric rocker switch on the dashboard, keeping air lines outside the cabin.

6. Do you provide OEM or customized services

Yes, we support OEM and customization, including nameplate, packaging, and specific performance requirements. Send us your drawings or specifications for evaluation.
